Develop a system that lets me signup with whatever sponsors you're working with easily. Say you have 200 sponsors, let me signup with 1 form (yours) and allow me to one-click signup with whatever sponsors are needed to filter and convert my traffic the best. You would get the referral of course, for the sponsors that have the option available. Maybe you could shave a % of the traffic for the ones that don't.
Maybe I enter a list of domain names, like I do with Sedo or other parking services. I can optimize a keyword or phrase for each domain in addition to categorizing it by niche. If I own Asiansex.com you can then start testing the traffic by rotating appropriate asian site sponsors, sending a % more to the better converting sponsors.
My main focus would just be sending you traffic. Your job would be filtering and converting it.
Examples:
www.realgranny.com - keyword style
www.adultfriend.com - portal style
Adult domain/traffic system based on PPS/Revshare instead of PPC.
