Is anyone familiar with Faronics Deep Freeze or Anti Executable?

It would be used in a couple public computer labs with several hundred computers each that are generally always infested with some trojan horse, spyware, or a virus. I am interested in the product because it would essentially allow people to get all the spyware infested crap in the world and at a scheduled time the systems could simply reboot, restore the computers to their original state and propagate updates. In combination with a base Ghost restore image that we already use every two months – it sounds almost too good to be true, no? I actually just found Deep Freeze the other day so that's why I'm asking of anyone else out there has access to the program and knows if it has any weaknesses or dark secrets that I may not know about just from reading their propaganda sales materials.  From first glance it appears to be just what we need.

Any comments would be greatly appreciated.
