As of the EuPC in Bulgaria I have embarked on a new project. I am researching the Permaculture vineyard. Every permaculturist I know likes wine, which inevitably comes from monocultures. There is precious little info on the internet and no book that I know off. If you know of any projects integrating vineyards in a permaculture system or have a project you want to convert, please get in touch. I hope to publish my findings within a couple of years.
