There was an interesting discussion on a similar topic over on the Newfound Woodworks board quite a while ago, the link is below. It started off as a question about the cost estimate of building a canoe (?), and quickly progressed into a debate on design rights. I think it was Mark (?) who "brought" the discussion to this board, but that one, I think is in the archives, which STILL isn't working. :-) Nick?
