Here, via the Bruderhof, is an article on intentional communities:All Things in Common.
I hope to get a chance to make several comments on this later, but let me say I was impressed that it wasn't a whitewash job on how "easy" it is to form a community. I was also quite taken by the implication that the community is unlikely to be permanent or static--that it must grow and change and then, perhaps, die to form something new.
