OK, so, I read through the first bout of posts, to page 13 or so, then skipped all the silliness that followed.
If anyone's still actually interested in this I have a few thoughts.
First, a Co-Op model seems better than a Commune model. Smaller group, focused upon a specific building/property, in or on the outskirts of the urban area you're already located in.
Allow for transferable equity interests (shares) and voting rights. Standard 50% or 66% quorum requirements for decisions. Incorporate the Co-Op as a 501(c) or similar and have monthly dues. Allow for people to make non-cash contributions for their dues through an appropriate approval process.
A pipe dream geekhive will never happen. Smaller 7-20 Co-Ops are thriving and successful. Take that model, apply it to the area you already live in, and generate/find interest in social groups (Bay12) guaranteed to provide some minimal amount of common interest and camaraderie.
I actually got really excited about this as I read through the first 12 pages. Unfortunately (fortunately?) I'm engaged and have accepted a job offer for next year, so I have no geographic/housing flexibility.
But it could work. If you actually wanted it to and took it seriously. I couldn't join, but I'd be happy to draw up documents, file legal forms etc... for anyone interested enough to actually do it.
