Watchdog software?

[Grey Knight]

We have a game room of PC's at work, and I'd like to get CivII going on them. However I don't want to leave the CD laying around for any ol' person to walk off with. I could use the no-cd executable, but I don't want anyone using it to pirate the game. Is there any way to secure it on an NT 2000 box such that it can be executed, but not copied / read?

Thanks,
Shawn
