Thanks.  Compared to most of the other postings, I tend to try to make POV 
give real-world results, which includes total internal reflection and light 
attenuation.
To tell the truth, I have no experience in any other renderers, especially 
scan-line, but for some reason, noone seems to be getting the total internal 
reflection effect properly.  (Or perhaps they are avoiding it for artistic 
reasons...)
