I came across a group in Chico, CA called GRUB (growing resourcefully uniting bellies). Their mission is to grow as much food within the city limits as possible. Distribution will be through a combination of CSA, barter, and free distribution to disadvantaged individuals, all on bike. They already have more donations of land then they have gardeners to work. They're also creating a "tree registry" - a list of fruit and nut trees owned by individuals who are happy to have others come harvest/gleen.

Another food system I like, which I understand has happened at times in both Chico and Eugene, OR is a "food swap." People who garden gather at a certain time and place and trade excess produce they've grown in their gardens.

Eugene also has the Grower's Market, a volunteer run food co-op. Because of how it's run it has the best prices in town. It's only open during certain hours on certain days, and, from what I hear, it tends to be a bit disorganized, but these seem like solvable problems.

Food is so crucial to people's lives and to building community. It seems like one of the easiest things to organize around to create a system of mutual support outside the money economy. As Twin Oaks has proved, good organization and a little labor from a lot of people can go a long way.
