You're absolutely right, Danny.
I think a true open-source project could work, but it would take a mighty big "opinion leader" to start it and set up the basic idea.
From there, it's a matter of the idea catching fire among an audience, which then leads to members of that audience originating their own additions to the overall idea. I'm not sure a committee, collective, or commune can create such a project. I think that it comes down to individuals, and certainly an individual to kick the whole thing off.
If you want it done, do it yourself.
Still, this thread has been a very interesting and educational exercise.
