I'm trying it now on my new multiseat system...

As far as I can look at it it's a very good sollution for multiseat. Let 
the X server offer a display, maybe exist of more than one screen (every 
monitor a different screen), which is the way to go with a videocard 
with two heads, offer these different outputs as screens using Xinerama 




and make the "normal" display, where the login will be:




where the "source display" of :0.0 is :99.0, and for :1.0 is that of 
course :99.1

I'havent been testing this yet, but is this possible??

And futher, is it also possible to use a "NX" display as source? Maybe 
you know, NX is a protocol to have a remote display, like vnc, but then 
much more efficient.

And finally, what is so different compared to Xephyr? Is it basically 
the same technique or is it totally different??
