Hmm, I was actually only planning on point or sphere particles, though 
possibly a way to specify a particle object and a "rotational jitter" 
amount. I also wasn't planning on actual particle-particle collision 
detection, just attractive/repulsive fields.
Doing collision detection between two arbitrary objects would be very 
difficult, approximating them with spheres would probably be sufficient 
for most cases.

What would be very nice would be the ability to specify a macro for 
creating particles. The POV engine would pass position, velocity, 
temperature, age, and other particle data to the macro through it's 
parameters, the user would write the macro to create the particles 
themselves. I have no idea how to do this, but I do plan on looking into 
it.
