Maybe a person could suggest they keep there system "pure" the way they want it and let you setup some "enhancements" that people would pay for or would be ad supported (by google adwords (ads on the ads, I know that sounds kind of strange)) then share the revenue. I believe they just don't want to lose control but at the same time they want to keep there system "pure".
