This 'scattering photon mapping' is definitely an interesting idea.  I 
don't know it it will work efficiently in practice but that's difficult 
to tell.  Note that it is a completely different approach towards 
scattering than usual.

But your blob based technique could be much more efficient with Chris 
Huff's blob pattern.  This way you would avoid the need for the multiple 
object patterns and don't need a slow proximity pattern either.
