Very interesting, indeed. Does this mean that one can basically create classes 
that inherit from some class like persistent.Persistent and data is then 
simply stored in a RDB instead of ZODB?

What I'm curious is how transactions are managed; I currently use SQLAlchemy, 
but it seems that transactions are managed on the RDB-level only, which means 
that the object state is not in the transaction scope.

Another issue is data migration, which requires changes in the database model 
(altering tables etc.), so this might be also quite challenging.
