Let's make that week or day or class !

In fact I have heard of a system that auto reloads an image each 
midnight or so - I don't remember what that was.

Hopefully the friend is using the obvious things like: bios password, 
only boot HD, locking network access to specific mac address, etc, 
disabling auto-run of cd/usb, etc.

About the vmware notion: In the ms way, a powerful machine could be 
installed as a terminal server. Remove the hard disks from the student 
machines. Network boot the PC's to an linux LTSP server. Only one 
application would be available / installed: tsclient {Terminal Server 
Client}.

Install a master power switch that feeds all the student PC's. At the 
end of each class, ask the students to save their work {to their linux 
network drive}. Then cycle the power. Machines BIOS set to auto restart 
on mains application - in 3 minutes every machine has a spanking fresh 
image loaded. That can only connect to the terminal server {which is 
properly locked down}.

It might also be possible to config your storage file system to allowing 
save of only the document types that you actually need -
