Related but tangential question that we were discussing on the pygr[0]
mailing list -- what is the "official" word on a scalable object store
in Python?  We've been using bsddb, but is there an alternative?  And
what if bsddb is removed?

It would be very nice to have a moderately scalable (thousands to
millions, if not billions) cross-platform object store backend
distributed with Python.

sqlite could be one choice, but I haven't used it much yet, so I don't
know.
