Does this mean that if I branch from upstream an revision N, and then,
later, branch from upstream at revision N+M, the second branch will be
able to share the storage with the first one? (If so, that's great and I
remove my 0.1%!).

In Bazaar, currently, I can maintain my own branch in sync with upstream,
and microbranch from it cheaply, but I can't do that if I branch directly
from upstream each time.

There are at least two differences betweed the weaves and the revlib: The
revlib is local (=> fast access) and recontructible (=> no backup). For
example, I have a 100Mb quota on my reliable-backed-up-and-archived
webspace, but 20Gb on my local-and-not-backed-up disk. The proportions are
 different from person to person, but for most people, local disk is
almost free and unlimited (less than 1 dollar per Gb).
