I'm assuming that this is because radiosity uses some sort of random numbers 
in the generation of the data.  If that's the case, it might be a nifty 
feature if the user could supply a "radiosity_seed Float" to ensure that it 
used the same random seed.  Otherwise, the only alternative of which I am 
aware, is to create the radiosity data in advance of the actual rendering.

Just a thought.
