You break the contract if you don’t give them enough feedback, and you must keep a list of everyone who has had access to your (hosted) beta for six months after commercial release and surrender it upon request.

I may be a zealot and it does look nice, but since I work at a CMS company, I don’t want to touch it with a ten foot pole.
