I could see this working in a joint venture type of situation, but it fundamentally conflicts with the "work to live" philosophy. If I was a member of a research team in my profession (Mechanical Engineering) and this situation was proposed for a R&D group, I would adamantly oppose it. Collaborative working, in my experience, is inefficient. It makes much more sense to compartmentalize work, then upon completion, combine modules into a finished product. A certain amount of communication is required, but the process in not encumbered with meetings and group discussions. A fully collaborative organization, to me, presents a clear end-of-line scenario for my employment with any company.
I have noticed that, even on a rationalist forum, a lot of ideas like this aren't very realistic. A vanishingly small minority of people associate so strongly with their work that they would be willing to completely forfeit their personal life in order to further a business which they essentially have no stake in.
When I show up to work, I am there to get a job done. I don't subscribe to the culture of going out to drinks with co-workers and I certainly don't sacrifice my personal time and work-life balance in order to make my boss more money.
On the internet, I think that people hold the (incorrect) notion that there are groups of people profiting from noble and exciting business ventures of their own creation. In reality, there is no market for the betterment of mankind.
