You might be able to set up a login script with a lock file, such that if
the lock file exists the user is immediately logged back out.  Of course, I
haven't fooled with much more than the basics of samba, but I seem to recall
that sort of thing should be possible.  Of course, some way of deleting lock
files left when a system is shut down unexpectedly would need to be
implemented (perhaps a cron script that checks if there's a user logged in
for each lockfile in existance?).

Why are students only allowed to access one computer at a time?

Can't say anything about this.

I'm including the mailing list in the reply so wrong answers can be shot
down.
