Hey man, I think this is a great idea. I'm not sure about the location and regiment, but communes like this are totally do-able.. I've been looking thru intentional community listings for weeks now, but many of them are pretty extreme in their views. I would hope starting a commune wouldnt be to hard with a few decent cultivators.
I'll tell you right now that if the right oppritunity arose I would pack my bags a.s.a.p. and help build it from the ground up. Some places that i think would be really worth checking out would be Minnesota, Oregon, or Alaska.. There would be many things to take into consideration, but I do know land can be pretty cheap in those areas.
that ic.org is a great resource..
heres an example of a successful, thriving community like this:
