Your B-version would not be a feasible solution. The surface structures
leading to diffuse scattering of light in reality are in micrometer
scale. Even if you use that accurate geometry there would be no effect in
Povray.
Photon mapping right now is good for large scale computation of reflection
and refraction, but not for realistic simulation of the detail effects.
