Just another thought: I guess if you're only aim is to get those 
explosions right, you may get faster (in terms of development and render 
times) and propably better looking (yet not physically correct) results 
using some sort of keyframing: Put all the parameters of your explosion 
in an array, create as many states of it as you need and interpolate 
between the states with a spline. That way you can control the look of 
it to the last detail. You could even build your keyframes dynamically 
within the script to let the user change some parameters.

It would of course take some time to prepare the keyframes, but that 
would IMHO be nothing compared to writing a fluid dynamics solver. OTOH, 
a fluid dynamics solver for POV would be really cool ;)
