Multiple Workstations

I should clarify a few items.

1) The GUI on the client workstation needs to be available only to that
workstation.

2) Once I have launched the application that uses the GUI I could
disconnect as long as the application keeps running.  There is nothing I
want or need to see on the desktop.  

3) This process needs to be repeatable.  If the application ends and
closes I need to be able to reset the workstation state to begin the
process over with a clean start.  

4) The application is a purchased product.  I know it can be launched
from the command line when you are logged on at a workstation.  I need
to do this from a remote machine and with multiple instances.

Thanks

If you write your application in X (probably Unix/Linux hosted, unless
there's an X library for Windows), it'll be easy: have your "slave"
workstations run the application instances, with their $DISPLAYs pointed
at the master server's Xvnc instance.  Then connect to that Xvnc
instance with vncviewer from anywhere and see all the app. instances.  I
think there's an obstacle to aggregating all the displays if the
application is Win32, even with VNC server or Term. Server on Windows
slave boxes, because there's no facility to aggregate all those virtual
desktops from the slave machines onto one display (physical or virtual).
(A VVNC might do it. :)  However if you don't mind having one vncviewer
process for each slave desktop, then yes, a VNC desktop running as a
service (for automatic startup) on each slave box makes sense.

YMMV, FWIW, HTH, etc.
