Spanning desktop across multiple X servers...

["Thomas Chadwick" <j_tetazoo at hotmail dot com>]

First, an apology.  This is not, strictly speaking, a Cygwin/Xfree question.

I know it's possible to span a single X desktop (for lack of a better term) 
across multiple display adapters residing in the same machine.  Basically 
the 2 attached monitors behavior as the left and right halves of single, 
unified root window.

What I'm trying to find out is if it's possible to span a single X desktop 
across 2 display adapters, each residing on a different machine?  If so, 
what would it take to get this set up?

I guess it comes down to whether the "spanning" function is something 
handled completely by the X server, or if it's implemented by the Window 
Manager or some other piece of "middle ware".
