So if I get this correctly, there needs to be an API involved that 
could interact with DB, DBI or ZODB, much as the DBI layer abstracts 
MySQL, PostGres, ODBC, et al.

That actually isn't a bad idea at all, since the first thing that can 
be done is defining the abstraction layer for the API, then building 
the DB interface to it so that existing systems can migrate and keep 
existing systems. And then that can be extended to support the other 
data stores as time and need meet with resources and volunteers. 
That's probably the cleanest answer anyway, since the first thing 
that happens is you build the API into an existing system, so you 
isolate the complexity of defining the API and building in the new 
datastores.
