I work for a.edu and perhaps a solution we use here could be helpful if your main goal is a "clean" computer state at startup. We've (finally) moved to an Active Directory based network. I'm now building.msi packages to be installed by AD and use a startup script to install a program called Deep Freeze which prevents changes from being made to the system while it is in a "frozen" state. With Deep Freeze, any changes that are made to the system are removed on reboot. Any file storage is done on a networked home directory. Deep Freeze can be setup to "thaw" during the night for windows and virus updates to run and then "freeze" again after X amount of time has passed.
If a computer breaks and needs to be replaced, we can drop in a replacement PC, move it into the proper organizational unit in AD, do a group policy update on the box and it will install the appropriate software on startup (and with the exception of programs like VS.Net it goes fairly quickly).
I for one welcome our Spaceball overloards.
Sorry I didn't see that you had already posted about Deep Freeze or else I would have just replied to you.

I've added a 1680x1050 widescreen version.
For anyone too lazy to do it themselves, I've made 1600x1200 and 1280x1024 wallpaper files of the cropcircle image.
