I can in no way speak for the entire group as I don't know how much of this has been decided upon, but the idea I get is the same as with Blue Moon Tribe - mainly hunting-gathering, and some permaculture. But no raising animals (like pigs) for slaughter. (We could have chickens for eggs though, and over at Blue Moon we've talked about fish ponds, but I guess the latter counts as "raising animals for slaughter".)
And this is why I stress large pieces of land, because the more we're going to live off hunting-gathering, the more land we'll need.
