The concept isn't without merit - it's just that to date - everyone (who I've seen) that has tried to enter this market tends to over-"featurize" (with the wrong features) and then under-develops a product that would be successful.
I have gone back and forth with myself trying to decide if I should actually build a program that would not only work, but also be accepted the surfer, paysite owners and the webmasters who promote the programs.
Unfortunately, I've always had other projects come to the front of my "to-do" list and it's not something that I would like to run by myself after it was built any ways. I did however register the domains for it (intellibill.net and intellicharge.net) for intelligent billing and charging

- sorry, no cooking ingredients here...
Any software program that offers paysite owners a fraud proof system, 0 reserves or hold backs and no charge-backs as well as eliminates the need for cascade billing is worthy of pursuit.
I certainly have the resume' and reputation to build it and if someone (and when I say someone, I should either know you or know of you), has contemplated entering this market and wants to manage it once it's built - give me a shout and we can talk about it.
