I don't know how this was accomplished, but at my university (using hpux) there was a way to register ip addresses with the hardware address of an individual ethernet card. The only way you could get ethernet access was to register your hardware address. If you tried switching your ethernet cards in your computer, you would have to re-register your new hardware address. So there must be some kind of way to check/supply this hardware address over the network.
But don't forget: The "evil student" could easiely sniff the NFS file- handels and then mount the directories from the NFS server.
