Holy crap! I messed around with Renderman-compliant renderers with "Maya integration" -- yea right, I had to rebuild every danged shader or texture in my entire scene to be RIB compliant... talked to a friend who worked with RAT and PRMan and aparently its exactly the same for the real deal too.

Maybe we just both are idiots and didn't see an easy way -- but regardless I hope this solves many issues.

Just for 1000$ too --
