This software needs to send a signal to a server (we will provide.) The goal is to lock out a computer if customer does not make his payments. Server side will be handled by us. All you need to do is create a script to send dummy responses for testing purposes. It doesn't matter much what language you use to develop this as long as the source code is made available. Look at the attached word document for details. Please explain (briefly) how you will accomplish this and if you have any suggestions. This must work on at least Windows XP-8. If you have a suggestion that will prevent user from being able to remove by just re-installing windows this is a bonus but not required.
