hi robert, we tried this with mesa at our latest training code. it didn't exactly work - problems cropped up mostly wrt extension features even though we had disabled most features which would require them. i didn't take the time to track down all the odd corners, given that vpb is a work in progress. and, if anyone wants exactly this feature, it's a great community effort. :) but it's good to know authoritatively that osgdem still requires a gfx context for some cases.
