Depends on what you mean...you can use an object with a high ambient
texture to do it, or you can use a grid of light_sources. If you mean
having area lights be calculated for all illumination instead of just
shadows, that would probably be nearly as slow as using a grid of many
individual lights, though a bit easier on the memory. It isn't a bad
idea, just hasn't ever really been needed...

"Ugly beauty"...
Well, this is probably happening because glows can get extremely bright
toward the center...sometimes radiosity will send out a sample that
happens to make a near miss, and the extreme brightness throws off the
radiosity calculation, making a "splotch". I have been thinking of a
"max_brightness" keyword to fix this...
