Yeah the media's one thing I need to fix and save back to the library...

Really, the thing that's making it slow is the refractive objects.  I 
could slap no_image on them and get the nice media/photon effects in a 
few minutes.  Turn off the media and photons and have the tetrahedra on 
and it takes a few days.

Is there any way to speed that up?  How do commercial renderers compare 
speedwise for refractives?  What do they do differently?
