Okay Alan, I've had 3 or 4 folks over the last 36 hours claim that X is 
its own forwarding agent, why am I even using ssh? saying I'm not 
needing ssh at all.

So, where can I find the definitive tut on doing this because our 
attempts are failing?  What I was able to find on the xorg web pages 
last night was up to 3 major versions out of date.  I need a tut that 
deals with X11R7 and up.  Is there such a thing?  My google-fu is 
failing me.

Thanks Alan.

Cheers, Gene Heskett
