It is already implemented and works just fine. By compiling Mesa with
GGIMesa and Xmesa support, with the GLX code hacked to use GGIMesa (like
the old Glide window hack), the dlsym-ing of Mesa is already coded and
works well. GGIMesa can use any rendering target back-end you can think
of. And none of it is tied to XFree86 or DRI - I was using XGGI and an
aalib target to run Quake3 at one point |->.
