The developers of Aqsis and MOSAIC have recently been working very hard on correctly exporting Blender fur to Renderman and the results are paying off very well. One of the major issues with Blender and Renderman is that the particle system in Blender is difficult to work with and up until recently had been impossible. Since Blender's fur system is based on particle data there was only the ability to export a general description of the fur to the RIB file but no way to actually control the fur. This makes for some ugly fur, let alone hair.
Now there is a way to export Blender fur using guide hairs! A lot of it comes from a custom DSO that handles the generation of the hairs based on the guide splines, so it's not so much a part of MOSAIC but the script does make calls to it using fragments associated with a particular shader assigned in Blender. There is also work to allow the layered shader function of Aqsis (note: Aqsis is the ONLY RiSpec renderer capable of this, not even PRMan can do this!!), so this allows for even more interesting work.
One of the projects in the works is some talk about rendering the entire Big Buck Bunny short using Aqsis as the render engine with little modification to the scenes. However that is only a rumor and not set in stone. hehe.
