The other thing to look out for in this type of situation is that the
school may have the ports locked out in such a fashion that the hubs
they're connected to will not accept multiple devices on one port.
Additional to that is the problem of IPs.  You can't just randomly assign
an ip, even if it's within the appropriate subnet.  This makes network
administrators very mad and vindictive.  You might find that your T-port
is no longer ethernet, and is now a 115v power socket.  Hope that your
roomie doesn't need his port.

If the ports are not set up to limit access to one device, you could buy a
cheapie 5-port e-net hub for about $60.  Maybe less if you look hard.  You
would hook that to the port on your wall, and it would become a repeater,
in essence.  You would then have 4 ports at your disposal.  Then you just
have to find IPs.

The video in the machine running the X clients does not matter.  The video
on the X server is what counts.  I had exported color X clients from my
IIsi to my SGI workstation (Over a ppp null-modem, no less) and it was no
problem.
