Thank you for that link. The idea that I and some other folks have been bouncing around is more along the lines of a shared R&D facility where members have a place to work, common areas to chat, facilities providing (and hosting) resources, with high speed access to the Internet. Badged 24 hour access and reasonable security.
That is in some ways like a maker space where paying your dues not only gave you membership it also gave you an office, shared access to expensive equipment, and medical/dental benefits. The stuff a "real" job gives you but without the (now unnecessary) salary.
The presumption is that the work would yield economic returns and if so, those returns would go back into the organization to offset the cost of membership. Of course if the cost of membership became negative then you'd effectively have an entirely employee owned corporation and that is where things get different. Some of the people I've talked to about this concept have created very valuable things in the past and they expect to again, if they did that in the collective's space how does that work? Does all that value flow to everyone, even people who didn't participate? How about to people who did but were only tangentially influential in the outcome. That is the "success disaster" that one has to create plans for so that what happens at that point has already been agreed to by everyone and we don't start suing each other.
There are other models, places like law offices which share expenses. Things like movie studios which essentially do a vfork(2) to create an entity to "own" a production and the results of that production, groups like the Royal Society (although I've been cautioned against creating something along those lines), and alternate forms of venture incubating[1]. There are interesting examples to look at like Willow Garage to see what worked and what didn't.
[1] One thought was to have this group of seasoned engineers get a project off the ground and proven then hire in a team to be the company, transition it to the team and move on to the next thing.
