This task would involve extensive testing of nmg->bot conversion logic, setting up methods to allow the raytracer to work on a BoT representation of the nmg (need to consider approaches - can the raytracer call the nmg->bot routine on a per surface basis on the fly, does it need to pre-generate the whole bot, etc).  It may very well be that the project would find fixing direct nmg raytracing is the best option for performance improvement, in which case the task would be to make those fixes.
