I see, that makes sense.

You mentioned all of the disks are going to be the same except for some 
configuration changes.  How are you planning on deploying these 
changes?    Why do those changes need to be different?

Are students going to snapshot the disk at any point?

As Jason was pointing out, I think the solution is more around content 
synchronization than running stuff from the server.

Maybe you use the main image as a "base" and then you create snapshots 
from that for each individual student.   The base image would already be 
on every student computer.  Therefore when they sit down you only need 
to copy in the "snapshot" portion of each student.

If you do this will may want to put swap and temp on a different disks 
to keep change set small; discarding those changes at the end of the 
session.

Their changes would be on their home directory.  When they login, they 
run a script that copies all of that data from their home to the local 
machine.

When they are finished, run the script that saves their data to the server.

If you do it this way, they can also do snapshots, since all of that 
data would get synced to their home dir.
