Lots of software and other engineers in here. Me, too. Steve Cooper at Curious Labs said so in a thread a while back. I think he is the Product Manager. That's where the 'renderman-compliant ratytracer' quote came from. He also said there would be hair and clothes physics (yum...:). Didn't mention collision detection, though. Search for 'Kupa' in the Poser forum. You should find his posting.
