Okay, heres the scoop.  The "double-headedness" of the X server (not 
manager) has to come from who wrote the X server. In other words when
Vitec writes their X server, they have to design it to control windows
on a Sun (our console) and the Vitec simultaneously.  Needless to say,
they did not design it that way.  

Some people have asked "Why not just start up 2 servers?"  Well, there is 
a serious problem with 2 servers not knowing who is supposed to get the input
from the mouse/keyboard.

New question: can you start an X server (not window manager) which ignores
all input.  This way the Vitec could be used as an output device only.

P.S. I really appreciate all the replies I received on my original posting. 
You folks are *wicked* (<- one o' dem Massachussetts terms) nice.  Thanx.
