OK I guess that makes sense. I guess the nVidia driver will need 
updating to handle this (I believe there is a problem with GLX on 
multiple screen mode vs. TwinView mode in that you can only use it on 
the first screen).

How does it handle the case where lots of applications are compiled with 
Xinerama support and they suddenly can't do what they were designed to 
do? I know the compositing mgr can do clever things with the multiple 
screens in terms of layout and other gubbins, but surely the 
functionality built into 100s of applications will then be lost?? Would 
a psuedo Xinerama plugin be created to emulate what the apps expect but 
on a multi-screen backend?

Sorry for perhaps going over old ground, and not being too knowledgable 
about all this, but my elation over this patch has suddenly just turned 
to dismay.... :(
