I was reading my "Linux Server Hacks" book and found a cool way to
freeze clients using root:
skill -STOP -u <username>
That causes all processes that belong to the user to freeze. You can
restart the user by:
skill -CONT -u <username>
It beats trying to run xscreensaver and remotely locking the other
computers (there are easy ways to disable/defeat that... I found out
pretty quickly as I battled students one day).
