Yep.  The demo CD runs "vncserver" automatically in a domain, which creates a 
virtual X display you can connect to using VNC.

Have you tried using SSH with X forwarding?  Just SSH to a domain using "ssh 
-X domain", then run an X application.  It should appear in a window, just 
like it would if you were SSH-ing to a real machine.

VNC, Xnest and FreeNX are also good things to look at.  SSH with X forwarding 
is probably the simplest.
