Sounds like there talking about a velvet shader there. Get on and disect it to find out how to use the sampler info node. is the best way.

how you put it togather might also depend on what you plan on useing when rendering. Do you know if you plan on useing the mayasoftware render on it ? or MentalRay with like FG on it ?

Let me know and we'll see what we can cook up.
