The lower layer consists of some C routines to exchange a memory buffer
between client and server (through shared memory or a socket) and the layout
of this memory buffer. 

Actually, local communication could be implemented using pipes or whatever
is best for your environment, as you have to port/implement both the client
and server side anyway.

There exist Python modules in the standard SAP DB distribution
(http://www.sapdb.org/framesets/sap_db_program.htm). Someone wrote the
beginnings of a Database Adapter for Zope
(http://www.zope.org/Members/jack-e/ZsapdbDA), it shouldn't be too hard to
finish it. Unfortunately, my own dabblings in Zope weren't very successful
yet.
