This may not be exactly what you need but maybe it will be useful to
someone.

To go from Ultrix to Ultrix (on TCP/IP) I have the following line in
my .login:

alias rterm "xhost +\!*;rsh \!* 'setenv DISPLAY `hostname`:0.0;dxterm & ' "

If I'm logged on to radagast and I want to start a window on frodo I type:

% rterm frodo

which expands to:

xhost +frodo;rsh frodo 'setenv DISPLAY radagast:0.0;dxterm & '

which does the trick. Of course my .rhosts file on frodo must have a
line that says:

radagast	rod

so the rsh command will work.

Understanding what processes are started is a little tricky. The rsh
command does not return even after the dxterm is started on the remote
machine. I usually just control-C after I see the message indicating
that the dxterm has started. You could also put the rterm command in
the background (% rterm frodo &) and then this command will show up as
stopped when you do a "jobs" command (thought the dxterm is just
fine). Further experiments are left to the reader ;-)

One last trick: you can give dxterm a command to execute when it
starts as in:

% dxterm -e my_application

This should let you start lots of stuff automatically.
