Do you mind sending me an email at j@jjcm.org? Would love to talk more.
I have some plans for 3rd party app revenue sharing I'd love your thoughts on. What I'm thinking is that with the $1/mo server fee I charge users, I'd carve out 30c of that as the "frontend fee", which I would distribute evenly between the frontends that user was using that month. If they were only using an app, I'd pay that app $0.30 for the month for that user. If they were using the app and the website, each would get $0.15 for the month.
