@Inspire: In TRADOC, the Army school proponent, students learn their job these days on a computer. The instructors had a lot of issues with students taking over the computers' settings, playing around with software like MS Paint and Movie Maker when they were supposed to be working and learning.
So, my software does a lot of what Phoenix does except it totally locks the user out of the system except for what we want them to see...Which is only the coursework.
If they manage to find a hole, it's detected and the computer is locked. Only an instructor can unlock it. The user has a login, so when they violate the computer user agreement, the violation is recorded for legal documentation.
It's currently installed on a few thousand computers across the army school system and hasn't been "cracked" yet. We've had professional computer systems administrators try to beat it, but they can't. Of course, when you have local access to the computer you can lock it down tight as a coffin.
