But you'd still be in a shared repo, you'd just *call* it "cache"!
That is, the cache needs to maintain the *same metadata* about where
to find a revision when needed as a shared repo does.

Really, you ought to just make shared repos the default, say that the
user's shared repo lives in ~/.bzr unless explicitly configured, and
worry about (better) garbage collection if and when people complain
about space.
