Ah, I would be interested in finding out more about those ancient healing centres too. It's in my to-do file somewhere! Sorry I can't help you in either case, but one of the current fasting retreats may be able to help you with your other question, or you could email a few and hopefully they'll give you a range of handy hints. If there are any local they would be best for finding out the legal side of setting it up and running it though of course.
