Thank you John and David. Now I'm getting it a lot much clear.

I'm a bit confused, as usual. What does "get the maps popped up on the
zLinux server" mean? I would have thought that the programs would be
running on the zLinux system with the "maps" displayed on the desktop.
If you ran VNCSERVER on the zLinux, that means that the X11 server (as
well as the X11 client) is running on zLinux and being "scrapped" by VNC
and sent over to the desktop, which is running VNC viewer. I don't know
why you'd do this. I tried something similar, but using VNC server on
Windows and VNC viewer on Linux. On a LAN it is OK. Across the Internet
it was painfully slow, due to my relatively slow DSL connection.
What I think should be done is run the apps on zLinux. The desktop runs
PuTTY or some other SSH client. It connects to the zLinux system, using
X11 forwarding. This will prompt for a userid/password (or digital cert
login) then open up a shell prompt (generally, it could open up a
different application entirely, if desired). The user would then enter
the name of the application to run on the shell. The output would be
forwarded to the X11 server on the desktop. All the graphics rendering
would be done on the desktop.
