There have been discussions of this sort made over the years. A good
place to start would be the old (well, maybe not that old) 6Net site where
there's a list of publications called 'Deliverables'. The info is buried
in other, but amongst other things it contains deployment scenarios as
well as cookbooks decumenting IPv6 deigns and roll-outs, and what they
learned from it all. Lot's to read, but good info nonetheless:
