Pretty cool to finally have a decent open 3d solution for windows vms. Now if only someone made an opengl driver for older intel macosx vms...
Not exactly what you are looking for... but I am working on a 32 bit intel mac emulator. OpenGL support is pretty far along at this point.
People are working on it!
