Hi,
last week Bobby Parker of the Blender Foundation
confirmed to me that RenderMan sup****t for Blender
(http://www.blender3d.org/)
has been implemented
by now (out of the Blender interface, not the *old*
approach via Python script).
This includes shader previews; NURBS sup****t, animation,
animatable DoF and more are yet to come. The RenderMan
sup****t works for basically *any* RenderMan compliant
renderer, such as Aqsis (http://www.aqsis.org/)
and others.
The software 'Neqsus/BtoR' can be found here:

Requirements: Blender 2.42 and higher.
