Heh, I'm still pretty hampered by having no clue ^_^

I originally missed the fact that it is completely irrelevant where in the chain the reference point is and that you can go easily from any arbitrary point in the chain to any other arbitrary point in the same chain. This makes it a lot more flexible than I thought. But to support more than just resumable cloning You would still need a more powerful way to negotiate "I have this; I want that" between client and server.

My point was mostly that lazy clone, sparse clone and resumable clone are closely related and should ideally be solved in one go. You currently seem to aim at only one of them, which is a shame. For lazy clone the client would start with all blobs referenced by HEAD (and possibly other branches) and then it would walk backwards through the delta chains if/as far/whenever it wants. Though it would also need to detect when it needs to start reading new delta chains as it walks backwards through history. Sparse clone would use the same mechanism and just restrict it to certain paths.
