Tom,
You may want to consider (if you
haven't already) looking into VNC (http://www.realvnc.com/
). Running a local Viewer, you take control of a remote computer running
a Server program.
I've used it to run equipment in a
remote observatory from home over the internet. It works well. You can also
connect computers each running different operating systems. The remote pc can
still be operated at its location. I haven't controlled more than one pc at a
time but I guess that could be done from within Linux.
That's easy with most client OS's. I regularly admin two Win2K boxes
using VNC at the same time. What Linux (and any other Unix type OS)
allows you to do is have multiple independent sessions on the same
machine at the same time.
Strangely, I've found over the years that using the java applet VNC client sometimes works better than the native compiled ones.

Just a thought.
