Not with this API.

This API isn't official. It's something I hacked
up. The original protocol was in the "PanoramiX" namespace
(the original name for Xinerama) and wouldn't even tell you
where the screens were at on the physical desktop - useless.
I've gotten some flak already for making my own protocol without
consulting X.org first. But then of course, if I waited for
X.org to approve it you wouldn't have any protocol today because
the official API still isn't finalized.
So, it's going to change at sometime when there's an official
API. XFree86 will be backwards compatible with the old
protocol but the sample implementation and all the commercial
vendors won't acknowledge the current protocol. You just have
to keep that in mind, and you'll be expected to rewrite all
your Xinerama awareness code at some point if you want it to
work with anything other than XFree86. The current solution
was a hack to keep the Enlightenment guys happy.

I misunderstood you. No there isn't anyway to do that.
