AFAIK Pixar renders (with RenderMan) usually push around 80 hours per frame on their film-quality stuff. And they seldom use higher res than around 1800x500 (~2K 2:35 size). So this could surely be used in production since they now have network render and collaboration render built-in to v1.0.
Very nice stuff man. That flashlight render of the kitchen had me fooled for several seconds!
