If they're just subscribed to a display he controls, ideally using a
client which supports multicasting, that's not a huge deal.  If he's
actually controlling theirs, I give it a half hour before the other
students figure out how to disable their own client + enable
themselves to control other students'.  "Teacher, Johnny's browsing
porn again!"  Heh, that's funny every time I imagine it.
