Yeah, pretty much.
I think we've got the Right representation for successive revisions of
a filesystem, but I don't know what sort of metadata is best for
producing minimal deltas between them. It's easy to construct good
structures for diffing revision N to N+1, but structures that work
well for arbitrary N to M, and for one subtree of M to another subtree
of M are harder. The latter problem is the one we want to solve. I
think the quick relatedness measure provided by the RCS-style numbers
is a decent approach for now.
