I rendered in less than a minute as well.

Regarding the Carrara render I think you may be right.  There are alot of parameters in there for the different materials.  I got him very close to looking like he did in poser by just adjusting a few things.  In the end I just don't know - so add me to the list of people who really wants you to make these for other renderers as well = D

I just can't justify using poser to render when what takes hours there takes minutes in other programs.  My scenes also require V4 and Apollo and for some reason my poser doesn't like any more than 1 apollo in a scene at any given time - (murphies law it makes no sense, I know).

Carrara is just by far the absolute best 3d program I have ever touched - the ease of use and quality can't be beat.  - I'm gunna stop now before I start sounding like I'm putting on an Ad for it...
