I was wondering if people thought that using X over a long-haul
network (T1) was an adequate design for an operational system or
whether it would be just infeasible.

In reading some of the early X doc (Scheifler '86) it was stated that X
was intended for networks with a 50ms roundtrip time, or a campus wide
net.  But from Boston I seem to ping Washington D.C. in 40ms. and
Colorado in 60ms (T1 link).  I don't know if that round trip time is
sustained, but in running some sample X clients at such distances did
not seem to be a problem.  The limitation was probably the server on
my end (Sun3 X11R3).

It would seem to me that applications that have little user input 
(cut down on those round trip times) would work well under X.  The main
advantage is that I would not have to come up with an application
specific protocol to support the distribution of graphic information
to remote sites.  Any comments or experiences with doing this ?
Please email direct, I have a hard time keeping up with the volume.

					Thanks, Paul.
