  You get what you pay for, pal.

  You can do quite pretty stuff with povray's fresnel highlights and
variable reflection. It may require some fine-tuning by hand, but
I wouldn't call it so "outdated".

  Please post the algorithms on how they are done with raytracing and
I'm sure they will find their way into povray.

  Although not trivial, you can do blurred reflections and refractions
(using stochastic raytracing) with the current povray. It's not even
hopelessly slow.

  Not true. Are you using POV-Ray 3.1 or something?
