Yesterday I stumbled across http://www.cheaplandinamerica.com - among other options you can get 643 acres in TX for $127K. On a related note, sites like http://tinyhouseblog.com/ http://www.tumbleweedhouses.com/ depict tiny homes at low cost & complexity. Getting 10,000 people signed up to commit $2.5B for a turnkey socialist utopia may be rather optimistic, but a low-entry-cost growth-oriented plan might work. Put in a road, well, and 3G/4G tower and get this project started!
