Hi Alan, Hans, and Chicago style bibliography users,
3) I believe that Gavin (on CC:) is a user of the Chicago author-year model.
I’d like to use the Notes and Bibliography style in my physics book, with endnotes after each chapter. I would gladly participate by testing and providing feedback. I am using a patched-together \footnote solution right now, and it is not great. The existing "biblatex-chicago” package might be helpful for development, especially in selecting database syntax and perhaps in designing algorithms. The author, David Fussner, has been maintaining and updating since the first public release in 2008. It the extensive documentation, he invites contact. It looks like a complicated project! I’d be happy to discuss this more at our next Norther Colorado ConTeXt User meeting. Would some time next week work? (Alan, who I met on this mailing list, lives a short bike ride from my house.)
