Is this something you'd be interested in helping me explore?
I just wanted to point out this joint copyright issue. I guess most hobby enthusiasts are not aware of this. If people do join up to create a thing together and to not have some contracts, best written down, they end up with that strange copyright situation, where everyone has all the rights, and could sell individually, but would be required to share the profit. Which sounds like a nightmare, if the group breaks apart mid project or someone suddenly wants to remove their contribution. Or when people disagree about how much share they should get...
So I wanted to express that this is a good idea, to give people some structure for this. I consider "rev share" a bit of a fuzzy area between hobby projects and semi professional works, with a lot of wishfull thinking involved. But maybe I am mistaken about this a lot.
