Your experiments are the best hair simulations I have seen so far. One 
way or another, it would be worthwhile to see if this could be used for 
Poser Hair exports through Poseray: If the /lines/ there could be 
exported as splines, sphere_sweeps would be an easy matter. Hmm, would 
need also an automatic sphere_sweep builder for so many hairs... ;-)

I believe that render speed is not really an issue if the final result 
is astounding.
