Hmm... this looks interesting. I think, but am not sure, that we could 
simply use
the OpenGL Z-buffer to figure out the "3D" effect and we should be able 
to generate
the 3D image -- or we just suggesting pure display of two framebuffers 
(sent from the
CPU, either software OpenGL or some other video card) that are mixed
on the two DVI outs? If we are just displaying, this should be really 
easy. I don't think
that generating them would be much harder, since we have all of the 
OpenGL set up.
We can rasterize the pixels once and offset in a second framebuffer 
(for the other eye)
based on the Z value, then take these two framebuffers and combine mix 
them to the
two DVI outputs.

Interesting idea!
