Like I said on the forums, this would require a major
rewrite of all the particles code. AFAIK, the only
coding we could be able to reuse the the particle
drawing code (or even that).

I am more than willing to help on such a rewrite,
especially since I have most of the algorithms/code
samples for that of particles simulation (need I say
Dynamica). However, being not to experienced in C/C++,
integrating that alone would involve an awesome lot of
trial and error and/or bugging people for answers ;)

I'm more than to participate in a team effort to do
that. This will most likely be a pretty long project
demanding a lot of communication between team members.

Anyway, enough babling, I'm willing to go forward with
a complete rewrite of the particle engine, so whoever
want to help, raise your hand.
