awesome.

But really, this is why pov-ray never quite gets much of a foothold:  only
ingenious guys like you, Sam Benge, Jaime Vives Piqueres and a host of others to
imagine such tricks.  And even worse: some tricks that ought to be in the
software are seemingly always reinvented by newcomers, like stacked sky,
micronormals and this one:  it is a well known fact that the multipass approach
is the way to go and that radiosity does not play fine with reflections,
refractions, media and now SSS.

So, how about a multipass switch for povray, devs?  I mean, sure there's the
quality switches going from 1 (plain constant ambient light) to 9 (full with
radiosity), but the numbers going higher only add more effects, don't isolate
them from one another.  I know it's a postprocess to combine the results and it
is outside the scope of a raytracer, but then again, an IDE to write scenes is
also outside the scope of a raytracer.  At the very least, providing scripts for
such...
