In fairness no I don't!

I guess if you want a completely different Desktop folder then no, I
doubt anything based on Xinerama/xrandr can do that (I could easily be
wrong tho').

Aside from the files on the desktop tho', the scenario you describe with
having some windows on the right screen (e.g. Web browser or IRC client)
and some on the left (e.g. project files - perhaps an IDE like eclipse?)
then this is easily possible with xrandr/xinerama, it's just a matter of
putting your windows in the right place. If you use a WM like compiz or
an extension to metacity like devilspie or similar then you can (I
believe) force the different windows to display by default on screen 1
or 2, so open a new web browser and it'll always go to the right screen
by default (although nothing will stop you draggin it to the left screen
if you need it there for some reason.

I think I'm maybe missing your requirement somehow as I can't see why it
doesn't work the way you want it! I'm sure this is my misunderstanding!
