On a personal level, I'm pretty happy with beta<=30 radiosity. I can see 
where it can be improved somewhat, of course. I would be very unhappy if 
the render times got higher and higher with each new release. I would be 
worried that it might stay slow :S

I don't think it's as dysfunctional as you say it is. There is an issue 
with render-block-sized squares showing up sometimes, but changing 
pretrace_end to a lower value makes those artifacts vanish. Black 
patches show up also, but lowering adc_bailout fixes that problem (as 
long as it's not caused by reflecting or refracting objects).

The quality, the speed, or both? If I can still squeeze artifact-free 
radiosity out of pov.b.3.7, I'll be happy. As long as it doesn't take 
too long, of course.

I think if the POV-team is going to pursue a higher-quality radiosity 
implementation at the great expense of speed, there should be an option 
to use the old "broken" 3.7 radiosity if desired. But clipka seems to be 
concerned about the speed as well, so I probably have nothing to worry 
about :)
