Earlier this year we stumbled on the group
http://twelvetribes.org/ and have become totally charmed by them. The ones locally have a farm that 30 people live in. They have cows, goats, chickens, bees and a large vege garden and greenhouse etc. They also have a restaurant in the town to provide additional income.
They are a commune and everyone works at what they are needed for, or are capable of doing. Since there are 30 or 40 groups of them all over the world, some of the people travel to different locations to help with setting up whatever their specialty is.
When you move there you basically give your possessions to the group and everything (except wives) are shared.
We were very tempted to move there.
They practice a form of Christianity that seems to me like the Essenes. There is no hierarchy although there are people in charge of different tasks so that things can run smoothly. They practice Christianity in a very gentle way and the people are uber friendly. The children are very sweet.
They live in nice buildings that they built and their common areas are very nicely built. They have rules but it is very easy going place, not like a bunch of wild hippies. There are 3 generations of people living there and a bit of changeover as people can move to other communes in their system all over the world.
We have gone to their Friday night celebration a couple of times and love to visit.
Regarding food, they do buy a bit of food at this point such as fish but primarily produce their own.
