Has there been any further thought along these lines? I have this for my projects that currently reside in LeanPub and practically all of my work includes revenue sharing with collaborators, meaning most of it I can't host here. I strongly prefer being able to direct money straight to their hands from sales on a platform.
Strongly disagree with DaedalusMachina's points as even two-person collabs can have more hassle on the money handling than the rest of the project combined - especially if cooperating internationally - and those problems compound the more complex the and larger the collaborative group.
