Am delighted to have stumbled into this discussion and really enjoyed the comments/observations Ken Peavey shared in this forum. One of the enormous hurdles that saddles permaculture is the loss of tried and true land knowledge. When I was a boy, we had a number of neighbors who came out to Montana in covered wagons. These knowledgeable elders could also grow the best fruit, vegetables, poultry and beef and they did so totally self contained by implementing information that had passed down, word of mouth, trial and error, through countless organic generations. They practiced permaculture without knowing they practiced permaculture and kept the seeds and offspring that worked on "their place." But as Ken pointed out, 50 years ago the chemical farmer came into being while at the same time hundreds of years of knowledge was lost as pioneers passed away. Now, modern hands-on agriculturists are beginning to reach the land first person again and because of knowledge extinction must "reinvent the wheel." What this new surge will need is hands on experience and a pioneer mentality. The internet can be a guide but not a work buddy. Nothing is guaranteed. And perhaps most important, what works in one place may not work in another even if there is only a short distance separating the efforts so what a permie hopeful must do is go out and get dirty.
