Is there a used SVT Pro Racer s/w market?

[TripleTransAm]

Every so often I scoured some boards looking for folks who wanted to sell their licenses to their SVT Pro Racer equipment / software but didn't see anything. Is there such a market for this kind of stuff 'used'? I'm not sure I'm ready or willing to dish out the big bux just for the ability to tweak tranny shift patterns (I'm one of the sad few who is actually satisfied with a good MM's stock performance, engine-wise).

If there is a market, what's the usual price range?
