	Ah, would that I had such equipment *sniffle* :-)

Radiosity is not any more difficult than raytracing, as a matter of fact, 
raytracing can be used to aid in the calculation of form factors.   In the 
classic "hemicube" radiosity papers, they always rendered polygons against
the surface of the hemicube using Z-buffer.  It is much easier to use
a raytracer for the same purpose.  

I have thought of doing a radiotracer and releasing it under the same 
public domain status as my raytracer, but I haven't had time to clean up 
my raytracer more, much less start a new project.   Hopefully someday....
