Good points both - I'd forgotten that VNC worked that way.  In a previous
life, I had to administer an NT-based backup system using VNC (over a
Saturn cable modem link).  You'd move the mouse and then go out to dinner
while you waited for the update to come back.  It was probably the backup
server, though.  Legato Networker works (as much as it ever could) on a
big Alpha running Unix.  It doesn't cope well with an NT box, even if that
NT box has a CPU a million times faster.
