I'm not sure what you are saying, but my particle system was designed 
for use with persistent variables, so it wouldn't have to recalculate 
from the beginning for each frame.
The problem is that the objects in the particle_system environment are 
also persistent, I need to add code to remove them on demand, so the 
scene file can place updated ones in. And even if I do that, the objects 
are a series of still objects...a particle bouncing off a moving box 
shouldn't bounce at the same angle as one bouncing from a still box. The 
dynamic transforms and interactive objects will have to do for that...
