Determining the location of fixed access points in a school can be done once (e.g. by a deployment team). Precisely because of it's static server role, it provides fixed position information for very cheap. If GPS is available, it should be attached to a mobile node (a laptop), not the server! > I think my initial question regarding whether or not the hardware > is currently capable of implementing this system overall is a > definitive "Yes," so I should be completing my proposal this > evening.
