Please forgive my silence and I really do appreciate your attention to my problem.
I originally posted my question on the cygwin-apps list and at Corinna's suggestion I
posted it on this list without realizing that I was not subscribed. I only now have
seen your responses as I searched the archives. I can now provide a specific example
of what I am doing.
On one cygwin installation:
uname -a => CYGWIN_NT-5.1 dac1 1.5.21(0.156/4/2) 2006-07-30 14:21 i686 Cygwin
the following command on the linux client:
ssh wellsr start foo.exe
results in a windows console popping up with the application (foo) running in it.
control immediately returns to the linux console.
The key to this working is the following script ("start")
that runs on the cygwin machine:
#!/usr/bin/bash
#
# There must be no spaces in the title field of the start command
# Otherwise, this seems to work, but I don't know how!
#
#
export XAPPLRESDIR="C:\iss60\app-def"
cmd /c start /I \ $1\ $2 $3 $4 $5 $6
(obviously the last line is the operative one)
on another cygwin installation:
uname => CYGWIN_NT-5.1 wellsr 1.5.24(0.156/4/2) 2007-01-31 10:57 i686 Cygwin
the same sequence launches the application and returns control to the linux
console but in this case there is no console window on the cygwin side. The
application appears on the task list but no window exists.

I consider myself scolded. I probably shouldn't try to go any further
without actually trying to do accomplish it. But here goes.... The
OP could simply replace the remote shell with the app that is to do
the display (which in the case you suggested would be something like
"bash -c screen...."), and let screen virtualize the connection.
Warning - technically OT again, I know, like all Cygwin/X topics here:
Also connecting Unix-Unix or Unix-Cygwin with SSL requires accepting
connections via the X server, which in the case of Cygwin can be coaxed
into accepting connections via SSL, and then the app would have some degree
of compatibility cross-platform. Then the remote command might be something
like "xterm -e screen...." I don't see much point in arguing about etiquette
(Where is the cygwin-etiquette list, anyway?), but the vagueness of the original
posting causes me to suggest that there is no, "one way," to go about
accomplishing this task. (You didn't get the Window client-server thing backward,
did you?). Anyway, this remote display implementating would require a lot of
RTFM'ing.
