I would really enjoy being a part of that. Hell, if it wasn't such a huge undertaking, I'd offer to do it myself. (But then, I have no professional talent whatsoever.)What I would love is for a company to do something similar to Wolfgang's Open design, but specifically for 4th edition and specifically and adventure path, starting at level 1 and going all the way to level 30.
This way each module is funded before it begins, and if support dries up, patrons have no one else to blame but themselves.
I would be all over something like that, and I would think the patronage model reduces much of the financial risk?
I do think though that a model like that, 1-30 levels is very, very harsh. To give you an idea, look how long it takes Wolfgang to do any project. Close to 6 months, and that's just a few levels. I can't imagine the amount of time it would take to get all the feedback and things like that for a 30 level span.
