This is surprising, I remember meeting the founder and the Red Gate guys out at Business of Software 2009. They seemed very passionate and committed (I kept hoping they would use a marketing idea I suggested).
One thought might be that they are going to add it to one of the other Red Gate tools and sell it more in the way that Red Gate is used to selling tools. (not SaaS)
