I think there are enough solo developers -- solo either because they're the only person working on a project, or because they're the only person working on a specific part of a project -- that this could be very useful even without the headache of splitting money between teams.

I agree that it would be good to be able to handle larger teams at some point, but it might be easier to figure out how to do that after seeing how people used a "solo developer" version of this.
