Heh heh, I can think of ways to beat the program. You load up a PC-Anywhereish program (like VNC) and catch someone in the act (record it). Then when they leave for bathroom/coffe/meeting/for more slacking off, install a cpu slowdown program and set it to run at a certain time to slwo the machine down to 1%. Tehn walk up to the guy at this time. Watch the reaction on his face!
Of course, you'd have to detect the guy first. If the guy can go without detecting suspicion from the boss/co-workers/etc, then he deserves to use this program. Most people who would use this program know jack about going undetected. Like that friend who left a quake desktop icon on his machine.
