Responses follow, but first a question.
Three elements of the model I am thinking about involve aspects of Twin Oaks, Alpha Farm and Ganas, and probably more, but I haven't gotten very far with that yet. This project will evolve with its own experiences anyway. I'll be writing a community proposal when I get this monograph and a few other things done. From this you are assuming that people only work for money. Certainly I'm not making that assumption.
