I haven't tried that, no.

How does the sharing of mouse/keyboard work when multiple X sessions are
running? Also, would I still be able to move the mouse seemlessly between
them and drag and drop icons (but not windows) between them?

I'm hoping there is some way to get an accelerated triple head setup working
with KDE4 as it's one of the only things holding me back on 3.5.10.
