There's my own effort for pseudo-sss a few years ago. It isn't a volumetric
implementaiton either, but it takes into account internal and external
obstacles. It should be slower than yours though, as it shoots many rays per
surface intersection.

An implmentation idea for faster and more realistic sss could be to piggyback on
the caustics photon mechanism.

Keep up the great work!
