OpenGL has to be one of the lesser used features of BeOS. If you use MESA to drive an OpenGL API even for R1 the number of programs that will be broken would be so few as to not matter at all. It seems to make sense to use MESA's code base unless someone thinks they can truely make an optimized version.

I don't know how up-to-date it is, but that would certainly be an excellent place to start.
