Great to hear another person interested in bringing opengl to matplotlib!
Another project you might be interested in collaborating with is Glumpy:
http://code.google.com/p/glumpy/
>From my limited knowledge of OpenGL, what my vision is that any of the
existing backends have support for an OpenGL object, so we just need to be
able to instantiate the opengl object in any figure object, and know how to
send it the appropriate commands and data. So, it is not exactly a
backend, more of a "middling". Anyway, I think the dev at Glumpy would be
happy to have help, and probably have much more developed ideas on how to
integrate with matplotlib.
Cheers!
