Interesting you should mention these, since ZODB provides transactional, 
transparent object persistence.

This discussion makes me wonder if Zope has been dabbling in AOP 
concepts for years without knowing it.  In addition to ZODB, Zope lets 
you declare permissions for methods, wraps objects with proxies to give 
them an environment, and inspects method signatures to make them 
directly callable by URL.  The AOP folks talk about very similar things. 
  Surely there is some common thread.
