I imagine a simpler approach is to use ZODB.  One possibility is,
instead of FileStorage or BerkeleyStorage as the underlying, use
something like _MySQLStorage_ or _OracleStorage_!

Writing the abovementioned new storages is left as exercises for
the reader. ;-)

Hmm, I wonder: MySQL doesn't have transactions, yet. Does wrapping
it with ZODB provide sufficient transactional functionality, while
retaining its high performance?

Maybe we can bring this thread over to Zope-Dev. I've been putting
off subscribing, I guess I have to now. ;-|
