Well, compared to other rendering solutions out there, it comes out relatively cheap. For example, the renderer used by DAZStudio is free only for the first license. Subsequent licenses are $1000 per hit. Aside from your "open source Renderman" solutions - I do not think you'll find one with P6's capability at near the same price. That, and I believe there is possible "corporate licensing" available from EFrontier (it is mentioned in the EULA). Pose-Net can also be used as a "batch rendering" mechanism even with one license. --EK
