I'm testing programs on different computers with different OS. One runs with Windows XP, one with Windows Vista and one with Windows 7. Instead of running each test 3 times I would really like to be able to run it all at once controlling all 3 computers with one keyboard and one mouse simultaneously. This would help me save a lot of time and simplify the testing as I will know the exact same thing would be done on all 3. So if one breaks it would be the Os not that I did something lightly differently the time I tested the program by manually switching computers as I'm forced to do today through a switch. Hopefully it would be some sort of system that I can expand on when I get more computers to run extra OS on.
