1. A method for location based control of nodes at multiple locations, the method being performed by a control device, the method comprising: identifying a first location by the control device, wherein the control device includes a control device key database having a first encryption key for communicating at the first location;mapping by the control device a control function that is stored on the control device, wherein the mapping occurs based on the first location such that the control function, while the control device is in the first location, results in a first action being performed in relation to a first node, wherein the first node includes a node key database having a list of approved keys for communication with the first node, and wherein the node key database includes keys for more than one control device;communicating with the first node at the first location, wherein communicating with the first node comprises sending the first encryption key from the control device key database to the first node to authenticate the control device with the location;identifying a second location by the control device;mapping by the control device a control function based on the second location such that the control function, while the control device is in the second location, results in a second action being performed in relation to a second node, wherein the same control function performs a different action in the first location and the second location such that the first action is different from the second action; andcommunicating with the second node at the second location, wherein communicating with the second node comprises using a second encryption key to communicate with the second node at the second location. 2. The method of claim 1, wherein identifying the first location comprises attempting to connect to a control network. 3. The method of claim 1, wherein identifying the first location comprises attempting to communicate with the first node at the first location. 4. The method of claim 1, wherein identifying the first location comprises determining the ability of the control device to control the first node at the first location. 5. The method of claim 1, wherein communicating with the first node at the first location comprises controlling the first node at the first location using the mapped control function. 6. The method of claim 5, wherein controlling the first node at the first location comprises controlling the first node over a wireless network. 7. The method of claim 6, wherein the wireless network is selected from the group consisting of: an infrared network, a ZigBee network, or a WiFi network. 8. The method of claim 1, wherein the control device is installed in a car, and wherein the control function comprises communicating with a garage door opener. 9. The method of claim 1, wherein identifying the first location comprises using GPS. 10. The method of claim 9, wherein the control device comprises a key-fob, and wherein the control function comprises locking and/or unlocking doors. 11. The method of claim 10, wherein identifying the first location by the control device comprises identifying a first control network, and wherein identifying the second location by the control device comprises identifying a second control network, and wherein the first control network and the second control network both physically and logically separate networks. 12. The method of claim 11, further comprising using a voting algorithm and privilege levels to resolve conflicting control requests. 13. The method of claim 12, wherein the control device communicates through a control system with the first node. 14. The method of claim 13, wherein the control device comprises encryption keys for each of the nodes it communicates with. 15. A system configured for location based control of nodes at multiple locations, the system comprising: a control device comprising:a processor;memory in electronic communication with the processor; andinstructions stored in the memory, the instructions upon being executed cause the processor to: identify a first location by the control device, wherein the control device includes a control device key database having a first encryption key for communicating at the first location;map by the control device a control function that is stored on the control device, wherein the mapping occurs based on the first location such that the control function, while the control device is in the first location, results in a first action being performed in relation to a first node, wherein the first node includes a node key database having a list of approved keys for communication with the first node, and wherein the node key database includes keys for more than one control device;communicate with the first node at the first location, wherein communicating with the first node comprises sending the first encryption key from the control device key database to the first node to authenticate the control device with the location;identify a second location by the control device;map by the control device a control function based on the second location such that the control function, while the control device is in the second location, results in a second action being performed in relation to a second node, wherein the same control function performs a different action in the first location and the second location such that the first action is different from the second action; andcommunicate with the second node at the second location, wherein communicating with the second node comprises using a second encryption key to communicate with the second node at the second location. 16. The system of claim 15, wherein identifying the first location comprises attempting to connect to a control network. 17. The system of claim 15, wherein identifying the first location comprises attempting to communicate with the first node at the first location. 18. The system of claim 15, wherein identifying the first location comprises determining the ability of the control device to control the first node at the first location. 19. The system of claim 15, wherein communicating with the first node at the first location comprises controlling the first node at the first location using the mapped control functions. 20. The system of claim 19, wherein controlling the first node at the first location comprises controlling the first node over a wireless network. 21. The system of claim 20, wherein the wireless network is selected from the group consisting of: an infrared network, a ZigBee network, or a WiFi network. 22. A system configured for location based control of nodes at multiple locations, the system comprising: a control system; anda control device that is in electronic communication with the control system, the control device comprising:a processor;memory in electronic communication with the processor; andinstructions stored in the memory, the instructions upon being executed cause the processor to: identify a first location by the control device, wherein the control device includes a control device key database having a first encryption key for communicating at the first location;map by the control device a control function that is stored on the control device, wherein the mapping occurs based on the first location such that the control function, while the control device is in the first location, results in a first action being performed in relation to a first node, wherein the first node includes a node key database having a list of approved keys for communication with the first node, and wherein the node key database includes keys for more than one control device;communicate with the first node at the first location, wherein communicating with the first node comprises sending the first encryption key from the control device key database to the first node to authenticate the control device with the location;identify a second location by the control device;map by the control device a control function based on the second location such that the control function, while the control device is in the second location, results in a second action being performed in relation to a second node, wherein the same control function performs a different action in the first location and the second location such that the first action is different from the second action; andcommunicate with the second node at the second location, wherein communicating with the second node comprises using a second encryption key to communicate with the second node at the second location. 23.
