Yeap, I'm working on some explosions/missiles/gun-fire right now.

One of tricks You mght find usefull:

sphere { 0 10 media { ambient ...   turbulence 0.1 } } - the fire

and now:

sphere { 0 10*2
  pigment { ... }   finish { ambient 0.3 }   	
  no_image no_reflection no_shadow
}

the second sphere, if rendered in MegaPov 1.1 - generates _only_ radiosity 
data. It could be used for example to better lighten a big room, there is a 
better chance for radiosity-ray to hit the "bounding" sphere and therefore 
to generate light, while with low count-quality some rays may not hit the 
smaller sphere and generate unwanted radiosity errors.
