Using X Windows remotely from cygwin

[bruce woller]

Douglas:
Are you locked in to Cygwin?  If what you want is to display a YDL (or 
MacOS for that matter) Xsession back to your Windoze box why don't you 
try VNC.  Start the server on YDL and the viewer on Windows - establish 
a new connection, set your password and you have a complete Xsession.

FWIW,
Bruce
