Skip, try this link here (it got a little contentious toward the end but still some good info).
Also, if you look on the left hand side of the front page there is an affiliates link. Not only does it go to a list of all CF affiliates (who I guess would be a good source of the info you are after) but also a reference to CFJ 35 which goes into some depth about opening up a CrossFit facility. From memory, I think there is an annual franchise fee of something like $US500 for commercial operations.
Hope this helps until other more knowledgeable folks pile in.
