Realtime update of database

We have a MS Access application that logs people in and out. All the computers running this software should see each other via WIFI network and update each other as to the information they have logged, realtime. If the computers are out of range, each should store the information in such a way that when it does see a computer running the software, it will share the information between them and update each others log. The computers will then have identical information. It should also have the ability to save which computer the information came from in the master log. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
