Well, I've got enough info to write one by now... only, not having
reviewed or tested the code, I couldn't actually vouch for it.

But seriously, coming to Zope for an app server, I had no idea that ZODB
was as robust as it seems to be. I think, from a marketing standpoint
for the Zope corp (and other in the community deriving sustenance from
providing zope-related products and services), it would make a lot of
sense if they at least made the claim in a prominent place that ZODB was
a serious candidate to replace a RDBMS if you didn't absolutely need
SQL. Collecting the info together could be put on the "todo" list, but
motivating people to seek it out would be a good first step.

Great.
