we've been using up to 8 projectors, using 3 triplehead2gos
the main problem we had was, that our gfx-card was only able to render
max.textures of 8192x8192, which means, you cannot create a gemwindow
that is bigger than that. (note that both width and height are absolute
boundaries, so you cannot use a 10000x1000 window with the above setting).

another option would be to use chromium [1], to distribute the output
rendering to serveral client machines, but i never tried this in a
real-world application (and afair, you might not be able to use modern
things like shaders)
