First, I need to explain something. The link I gave to PPFX needs a
disclaimer on it. I am not suggesting by any means, that we need to port
PPFX. PPFX, is a post processing plug-in that analyzes the Z-buffer of the
rendered image, and uses it to decide how to render the particles. So,
basically, I'm suggesting that we keep the rendering part of the current
system, but update the calculation code to add the following features:
1. Vortexes 
2. Jitter value for almost every value 
3. Key framing for all values 
4. The amount of particles be based on a "flow" value, and not on an
absolute one (the value would represent about of particles released every
frame, not the total amount of particles in the system)
5. Uniform distribution of particles (a large face will emit more particles
than a smaller one in the same object)
6. Gravitons, Fans, etc. 
I'm perfectly willing to help code this. Currently, I'm busy working on
cloth support, but I will be glad to help in any way I can.
