Look at the window manager spec on http://www.freedesktop.org, I think
it has some kind of layer hints. But don't count on it always working
- if nothing else, what if another window also asks to always be on
top, the window manager is going to have to deny one of you. ;-)

Poking in Xinerama.h, this looks promising:

  Bool XineramaIsActive(Display *dpy);
