Yes, I'm looking into it, possibly combined with SDL_GL_LoadLibrary

Why do you think it might cause issues? Either way, so far it realies on the GL/gl.h header,
currently I am only targeting OS X and developing on Linux, using -vo gl via SDL on Windows
or anything is not yet a consideration for me.
Of course if someone wants to try to get it working somewhere else I'd be happy to look
at patches.
