Yes, I saw this video a little while ago. I thought they made a very decent attempt at it, but I also agree with much of what has already been said here:
* It's almost an impossible task to do fairly.
* There's the speed of rendering and the speed / effort of 'set up' to consider.
* Speed is everything: if you have 10,000 frames to render and a tight deadline.
* Speed is nothing: if you've spent two weeks modelling, texturing and setting up a single still image and now need to render it.
* Who cares about speed? What about the looks!
* etc. : )
Bottom line: What a toolset! I started doing 3D when the thought of calculating any form of global illumination - even for a still image - was a pipe dream... Take your pick from a fantastic group of renderers.
