Thanks for this.  Rebecca is a great listener.  I was chatting away
this morning at breakfast, saying the following:

1. The only way to scale up Leo so that it could, for example, handle
data sets like the human genome project would be to store Leo's nodes
in a DB.

In such a situation, Leo files become "windows" or "views" on the DB.
Rebecca correctly points out that an individual Leo file can contain
multiple views of data, and this quality does not change if the nodes
are stored in the DB.

2. Basing nodes on a DB has the potential to allow cross-file clones:
the DB (potentially) can solve all the worrisome problems with
multiple access.

This has the potential to be a game changer as far as the *idea* of
clones, nodes and views is concerned.  I don't know how this will work
out, but just about every Leonista, including me, has wanted more
capable (cross-file) clones.

3.  The interaction between bzr and a DB is intriguing.  Perhaps we
will indeed use fossil, which I am just reminded is based on SQlite.

In short, I believe that this year will see a grand re-visioning of
what Leo is and can be.  This new vision has arisen more from the
usual suspects than from me--a development that pleases me greatly.

Ville, your code is an important step forward.  I'll commit it in some
form soon, and begin serious study of it as a way of priming the
subconscious pump.  Great things will come of this, I am sure.

Edward
