What is claimed is: 1. A method for using a wireless hand-held portable computer for vending machine communications, the method comprising: automatically receiving, at an application controller associated with at least a first vending machine, operation data from the first vending machine; automatically receiving, at the application controller associated with the at least first vending machine, operation data from a second vending machine; communicating the operation data from the application controller to the wireless hand-held portable computer; receiving a query at the application controller from the wireless hand-held portable computer; in response to the query from the wireless hand-held portable computer, automatically using a wireless interface of the application controller to transmit the operation data for the first vending machine and the second vending machine to the wireless hand-held portable computer; communicating between the wireless hand-held portable computer and a network operations center using a wide area network (WAN) interface; transmitting data for the first and second vending machines from the network operations center to the wireless hand-held portable computer via the WAN; transmitting the data from the wireless hand-held portable computer to the application controller; and communicating the data from the application controller to the first and second vending machines. 2. The method of claim 1, further comprising sending a query from the application controller associated with the first vending machine requesting other vending machines to provide operation data to the application controller associated with the first vending machine. 3. A system for communicating data for vending machines the system comprising: an application controller interfacing with a vending machine to acquire operation data from the vending machine; an application host communicating with the application controller via a local area network (LAN) to receive the operation data from the vending machine via the LAN; a wide area network (WAN) interface in the application host operable to transmit the operation data acquired by the application controller across a digital paging network to a remote transaction server; a transceiver in the application controller operable to receive the operation data from the vending machine and the transceiver operable to transmit the operation data from the vending machine to the application host; the remote transaction server communicating with the application host via the digital paging network to receive the operation data acquired by the application controller; and the remote transaction server transmitting data for the vending machine via the digital paging network to the application host; the application host operable to transmit the data to the application controller via the LAN; the application controller providing the data to the vending machine; and transmissions from the application host to the remote transaction server including messages transmitted across the digital paging network and stored in one or more dedicated message mailboxes for access by the remote transaction server. 4. A remote data acquisition and transmission system, comprising: first and second application controllers, the first application controller interfacing with at least a first vending machine to acquire operation data from the first vending machine, and the second application controller interfacing with at least a second vending machine to acquire operation data from the second vending machine; an application host communicating with at least one of the first and second application controllers via a local area network (LAN) to receive the operation data from the first and second vending machines; a first transceiver in the first application controller operable to transmit the operation data from the first vending machine to the second application controller; the first transceiver operable to transmit the operations data from the first machine to the application host; a second transceiver in the second application controller operable to transmit operation data from the second vending machine to the first application controller; the second transceiver operable to transmit the operation data from the second machine to the application host; the first application controller operating as a relay when necessary to establish communication between the application host and the second application controller, such that the first application controller relays the operation data from the second vending machine to the application host on behalf of the second application controller; the second application controller operating as a relay when necessary to establish communication between the application host and the first application controller, such that the second application controller relays the operation data from the first vending machine to the application host on behalf of the first application controller; a wide area network (WAN) interface in the application host, wherein the application host uses the WAN interface to transmit the operation data acquired by the first and second application controllers to a remote transaction server; the application host operable to receive incoming data for the first and second vending machines from the remote transaction server via the WAN; the application host operable to forward the incoming data to at least one of the first and second application controllers via the LAN; and the first and second application controllers operable to provide the incoming data to the first and second vending machines, respectively. 5. The system of claim 4, wherein the application host and at least one of the application controllers perform operations to autoconfigure the LAN, the operations including configuring the first application controller to operate as a relay for the second application controller when the second application controller is not within a primary communication range of the application host. 6. The system of claim 4, wherein the application host and at least one of the application controllers comprise a wire-line LAN transceiver for communicating via the LAN. 7. The system of claim 4, wherein the application host and at least one of the application controllers comprise wireless LAN transceivers for communicating via the LAN. 8. The system of claim 4, wherein the application host comprises a portable computer. 9. The system of claim 4, wherein the wide area network interface of the application host comprises a WAN wire-line interface. 10. The system of claim 4, wherein the WAN interface of the application host comprises a WAN wireless transceiver. 11. The system of claim 4, wherein the WAN interface of the application host connects the LAN with the remote transaction server via a narrowband PCS wireless link. 12. The system of claim 4, wherein: at least one of the first and second machines comprises a vending machine; and at least one of the application controllers interfaces with at least one of the vending machines via a serial interface to a vending machine controller. 13. The system of claim 4, wherein: at least one of the first and second machines comprises a vending machine; and at least one of the application controllers interfaces with at least one of the vending machines via a vending machine multi-drop bus. 14. The system of claim 4, further comprising: the operation data acquired from at least one of the first and second vending machines comprises product dispensing and inventory data. 15. The system of claim 4, wherein the operation data acquired from the first and second vending machines comprises equipment status data. 16. The system of claim 4, further comprising: a database in the remote transaction server, used to store the operation data; and a software module in the remote transaction server that provides secure third party access to the database via a web browser to connect to the remote transaction server across an internet based network. 17. The system of claim 4, further comprising: a second LAN in communication with the remote transaction server; and the second LAN containing third and fourth application controllers and a second application host communicating with at least one of the third and fourth application controllers, wherein the application hosts in the at least one LAN and the second LAN use a wireless two way paging network to connect with the remote transaction server, to establish an efficient and low cost wide area network. 18.
