Your question is more vague than you think. How fast is the connection
between the remote machine and the server? How much latency can you
tolerate? How many users will be connecting to the server at once? Can
you tolerate using non-Free software?

If you have fast connections between machines (>=100bT) then you can do
it with X over TCP or x11vnc or gino or KDE Desktop Sharing.

I am not sure what data rate you are referencing. 100bT? I confess, I do
prefer using engineering-style nomenclature, especially, when discussing
rates, etc.

To the OP:
IME, the performance of forwarded X session for simple X applications
(text editors, newsgroup readers, web browsers) will be acceptable if
the LAN provides at least 2 Mb/s speed. More speed is obviously better.
Your specific application could require much more bandwidth,
especially if you are using graphic intensive applications. As of now,
most standard wired ethernet LANs are using at least 100 Mb/s on the local
segment. If you get that speed (say, in another building on campus), then
almost any X application will work. But accessing that LAN segment from
more remote locations will most likely impose other bottlenecks and rate
limits. One thing to be aware of is that devices such as DSL and cable
modems often use an asymmetric rate allocation; upload speed is often
significantly lower than the device's download speed.

If you think you would like to try X forwarding, then there are numerous
tutorials on the web. ssh is often used to serve as an encrypted "pipe" in
which X is forwarded. The first step is to determine if login via ssh is
available to the system from a remote location.
