This is really impressive. Did you try to do a candle ? Does your 
technique work with a very close light ?

My guess for your technique is a two pass render, first pass with a 
black and white spherical pigment depending on the light position that 
you apply to all objects with subsurface scattering, and then a second 
pass where you use the first one to evaluate the color. While explaining 
my guess I have no really precise idea on the how you did it though.  :-)

Am I any close ??   8-p
