Predator - A USB Lock for your PC

Fascinating new piece of software that can be VERY handy. I have tested this and the alarm, btw, is LOUD. It basically uses any USB flash drive as a "key" for operation of your PC. It will do nothing with the key out - operates fine with the key in. There's also a strong-password option if you were to lose the USB key.

Great for laptops.
