A system for exchanging GPS or other position data between wireless devices for purposes of group activities, child location monitoring, work group coordination, dispatching of employees etc. Cell phones and other wireless devices with GPS receivers have loaded therein a Buddy Watch application and a TalkControl application. The Buddy Watch application communicates with the GPS receiver and other wireless devices operated by buddies registered in the users phone as part of buddy groups or individually. GPS position data and historical GPS position data can be exchanged between cell phones of buddies and instant buddies such as tow truck drivers via a buddy watch server. Emergency monitoring services can be set up with notifications to programmable individuals in case an individual does not respond. Positions and tracks can be displayed. TalkControl simplifies and automates the process of joining talk groups for walkie talkie services such as that provided by Nextel.

1. A method of determining positions of multiple users, the method employing a server, the method comprising: maintaining an account for a first individual, the account identifying a buddy list including the multiple users, the account accessible to the server;storing a last known position for each of the multiple users;in response to a first request from the first individual, retrieving at the server a map representing a first geography, the map selected in dependence on position of at least one of the first individual or one of the multiple users,based on correspondence if any between the last known position for each of the multiple users and the geography represented by the map, plotting positions on the map of each of the multiple users with the last known positions, andtransmitting the map with plotted positions to the first individual for display; andin response to a second request from the first individual, changing the geography to a second geography, andtransmitting a map representing the second geography with plotted position of at least one of the multiple users to the first individual for display;where the storing of the last known position for each of the multiple users, the transmitting of the map representing the first geography and the transmitting of the map representing the second geography are each performed in a manner not requiring concurrent voice communications. 2. The method of claim 1, further comprising receiving position information for the first individual, storing a last known position for the first individual, and, in response to the first request from the first individual, if the last known position for the first individual corresponds to the first geography, also plotting the position of the first individual on the map representing the first geography based on the last known position of the first individual. 3. The method of claim 2, further comprising storing a history of last known position for at least one person. 4. The method of claim 1, where storing the last known positions includes automatically receiving GPS position information associated with a built-in GPS device of a cell phone of at least one of the multiple users, in absence of contemporaneous voice communications. 5. The method of claim 4, where receiving the GPS position information includes receiving encrypted coordinates representing the GPS position information and decrypting the coordinates. 6. The method of claim 4, where receiving the GPS position information includes directly transmitting the GPS position information to a cell phone associated with the first individual. 7. The method of claim 1, where storing the last known position for each of the multiple users further comprises maintaining an account for each one of the multiple users, and where the method further comprises permitting individual ones of the multiple users to selectively turn location sharing either on or off. 8. The method of claim 1, where transmitting the map in response to the first request includes transmitting the map representing the first geography via TCP/IP packets and where transmitting the map in response to the second request includes transmitting the map representing the second geography via TCP/IP packets. 9. The method of claim 1, where storing the last known position of each of the multiple users includes obtaining latitude, longitude, and a timestamp for each of the multiple users. 10. The method of claim 1, where retrieving the map at the server includes picking a map centered on the last known position of at least one of the multiple users. 11. The method of claim 1, where retrieving the map at the server includes picking a map centered on a center of gravity of at least two of the multiple users. 12. The method of claim 1, where transmitting the map in response to the first request includes transmitting the map representing the first geography in a manner that is JAVA compliant, and where the method further comprises providing the first individual with an option to re-center the map representing the second geography on one of the multiple users. 13. The method of claim 1, where transmitting the map includes transmitting the map to a cell phone internet browser. 14. The method of claim 1, where transmitting the map in response to the first request includes transmitting the map to a remote application run by a cell phone internet browser. 15. The method of claim 14, where the remote application is JAVA compatible, and where the map representing the first geography and the map representing the second geography are rendered on the cell phone using JAVA. 16. The method of claim 1, where maintaining an account includes defining a default radius, and where retrieving the map includes retrieving a map corresponding to the radius. 17. The method of claim 1, where maintaining an account includes defining a default zone of particular size and shape, and where retrieving the map includes retrieving a map corresponding to the zone. 18. The method of claim 1, where maintaining an account includes maintaining the buddy list, and where maintaining the buddy list includes initiating a request to a specific individual, and adding the specific individual only if a response from the specific individual indicates that the individual has opted in. 19. The method of claim 1, where storing last known position includes for at least one of the multiple users receiving the position information on a configurable basis. 20. The method of claim 1, further comprising obtaining last known position information of the first individual, and making the last known position information of the first individual available to the multiple users identified by the buddy list. 21. The method of claim 1, further comprising hiding information of the first individual from the multiple users identified by the buddy list. 22. The method of claim 1, further comprising the ability to present information of the first individual from the multiple users differently to one or more users identified by the buddy list. 23. The method of claim 1, where the request from the first individual includes an EIN associated with a cell phone, and where the method further comprises authenticating the first individual by matching the EIN with a number associated with the account. 24. The method of claim 1, further comprising downloading, to at least one cell phone, application software to interact with the server to exchange location information with the at least one cell phone. 25. The method of claim 1, where changing the geography further comprises zooming the map from the first geography to the second geography in response to the second request. 26. The method of claim 1, where retrieving the map includes obtaining the map representing the first geography from a server of a third party map provider. 27. The method of claim 1, where retrieving the map includes retrieving a map of default geographic resolution. 28. The method of claim 27, where retrieving the map of default geographic resolution includes determining a geographic resolution specified by the first request. 29. The method of claim 1, where a specific one of the multiple users is associated with a time limit for location sharing, and where the method further comprises transmitting a map representing plotted position the multiple users excluding the specific one of the multiple users to the first individual for display. 30. The method of claim 1, where a specific one of the multiple users is associated with a time limit for location sharing, and where the method further comprises disabling transmitting of the a map having plotted position of the specific one after the time limit has expired. 31. The method of claim 1, further comprising, in response to a refresh rate specified by the first individual, transmitting an updated map to the first individual with the plotted positions to the first individual for display. 32. The method of claim 1, further comprising, in response to a change in last known position for one of the multiple users, transmitting a alert to the first individual, the alert responsive to a change in the last known position for one of the multiple users that is at least one of (a) a change in position toward a specific location, or (b) a change in position away from the specific location. 33. The method of claim 32, where the alert is responsive to a change in position to within a specific proximity of the specific location. 34.
