"Multiple shader types like Oren-Nayer-Blinn, Aniostropic reflections, GLOSSY reflections" You should visit the Material Room some time. "There's TONS of things that you can't do with Firefly or this Daz thing that you need for true realism and professional productivity." You do realize that most VFX shots in feature film production were rendered without all these features? You might want to read some of the production notes from LOTR or Finding Nemo to see how they faked their way to get around ray tracing. By your standards, PRMan would be a highly unprofessional renderer.
