Errr..., no.  The complaint was about VNC speed over a low bandwidth
link.  Running straight X is going to be much worse. VNC can skip
some steps during a screen update and catch up with the results when
things stop moving - X has to complete every step at the remote side.
Just opening a new window over a T1 can take minutes. Tight/ultra
vnc have some advantages but you have to match the client and server
to use the extensions.  However, I think there may be some kind of
network problem involved.  VNC over a T1 should be slightly annoying
with the cursor lag but very usable.  What kind of transfer rate do you
see in an ftp between the machines in question.
