Just picking up on old posts I hadn't found the time to read, so here's
some quite late reply...

Currently working on something along those lines, actually.

As for the combination of focal blur and radiosity, that won't fly,
because radiosity samples are cached and re-used, so you don't get
<blur_samples> * <radiosity count> secondary rays anyway. (That's
actually the difference in technique between POV-Ray and MCPov as far as
indirect illumination is concerned.)
It should work though for the combination of radiosity and other
multi-sample effects, such as radiosity and area lights. (Not sure off
the top of my head whether radiosity sampling currently honors area
lights or just simplifies them to point lights.)
