This idea reads like a joke, but there's something to it. One feature request: In addition to high-level milestones, it would be cool if a partially-funded project would generate a public, highly detailed implementation plan. Also, IANAL but MIT is still a license with a copyright holder. I don't think saying "it's MIT, we all own it" is defensible. The courts might view all this code as public domain.
Which market is even left after since the sasspocaloypse?
