[Zope-DB] Unified DA for Zope 2 using SQLAlchemy?

Now (in Zope2) we have things like ZOracleDA (DCOracle2), ZPsycopgDA
etc. that are adapters to these specific databases. They're based on
Shared/DC/ZRDB/.
In Zope3 there are also such adapters eg. one using cx_Oracle. They're
based on Zope3 rdb module.

What do you mean by 'replacing' them? You want wrapper build for
z3c.* to be used instead of ZRDB (rdb)?

You're talking about Zope2 or Zope3 too?

I don't fully understand what you want to do...
