So since Soni got me to setup raspbian on the old raspberry pi, I got PyOpenGL + GLES2 working on it today. There is a bug in raspbian's EGL library (it depends on GLES2 without linking to it), but with a work-around for that bzr head of PyOpenGL can run the bcmwindow example/raw.py demo. I *don't* have a spare HDMI cable, however, so I didn't actually get to *see* the demo running. Oh well, next time. bmcwindow is now up on pypi should people be interested.
