I know of a group of people doing something similar near where I live. They have successful serial eco entrepreneurs, experts in land acquisition, builders, teachers, and several doctors, involved at the higher levels. Not exactly a bunch of hippies. (Edit: If they were doing it somewhere more sensible, as in warmer, I'd be on their board as well. I think people should be encouraged to create intentional eco communities.)

They want to have full control and not all of the usual infrastructure required for a town like sewers, roads, etc. One of the major problems of course, is zoning laws, which can be circumvented by setting it up as a university... or a religion.

I skimmed through the omegaproject site and didn't see where it was planned or who was behind it, two things that would help. Without knowing more about the people involved, it does come across as suspect.
