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.=20
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.

Hi,
This system works completely different from Blender, and its 'features =
and limitations' page is quite disturbing... however, it does support =20
quite some more motion systems.
A proposal for a 'rewrite' can only be evaluated if you think someone's =
=20
going to do the coding and technical design for it.
If a discussion can be limited to defining a couple of features that we =
=20
see missing, then I can at least advise on what the feasibility is to =20
improve/adjust the current implementation.
