This looks very promising. I believe that the number of people who want to offer affiliate marketing options will boom if you show them that you can do it (with your app). In a sense, you'd be creating a market. Perhaps offer fees that scale down (even minimally) as my revenue goes up, so that our interests are more fully aligned? And it may be worth experimenting with a monthly fee, just to see if that helps keep out the "high-maintenance, low-profit" customers (or not).
