Abstract
A computer has one or more communication interfaces that determine if one or more client (client devices) is within a range of communication of the computer. The computer also has one or more computer interfaces capable of communicating with one or more of the second computers. The second computers can be at any general location and/or installed as subsystems of other devices. An application process determines from the client signal that the client is within the range of communication and that requests and receives one or more of the application programs through the computer interface from one or more of the second computers at the commuter location. Thus, the application program (and necessary databases) are moved to a next computer as the client moves within the range of communication of this next computer. The application programs/databases can be discarded once the client moves outside of the range of communication of the computer.
