Folklore says: the ZODB will almost surely not be your bottleneck.
Almost surely, the computation/rendering inside Zope will
become the bottleneck. You use caching and replication
to scale. For the replication, you need ZEO (search Zope.org
and the mailing list archives, for details).

ZODB is a framework with a "Storage" as missing component.
Provided you are using a Python with large file support,
the capacity of ZODB+FileStorage is virtually unlimited (some 2**32 objects and
as many data as fits into a single file).
>2. Is it possible to replace ZODB by MaxDB/Berkeley (or some other database) to improve the scalability? If yes, how can it be done?
Support for Berkeley databases was dropped recently (because of
lack of necessity).
