I work with 3D displays and my company has had a number of porn studios approach us to partner to do 3D porn. Personally I'm not against the idea, but I guess because of some of our other partners we don't want to be seen associating with porn.

Seeing it in 3D is an interesting experience though; I think it'll be popular with the voyeur-style porn. If done well, it really gives the sensation of being right there.
