Karl and I have been reading/studying docs on "changesets".

Yesterday we had a (hand-waving) discussion about how the repository
might implement them as first-class objects. It's interesting, but we
both have a common intuition now that our "genetic merging" idea is
probably 98% equivalent to storing changesets -- they may end up being
the same thing when it comes down to implementation. Pretty neat.
