Corba integration does not exist, but it would not be dificult to do.
As a corba client, you could take some third party python corba package
and integrate it into a Zope product to create "CORBA Methods" that
would word presumably like External Methods.

As a CORBA server you could create a new ZServer module.  Remember,
ZPublisher, the 'heart' of Zope, is an Object Request Broker (ORB) that
maps quite cleanly onto CORBA.  In the past when ZPublisher was Bobo, I
beleive there was even some work done to make Bobo corba aware, I'm not
certain.

In any case there has been no demand on us for it for a while now, corba
is not a very active standard.  XML-RPC seems to fill it's shoes quite
well.

It is not OQL compliant at all, however I see no reason why it would not
be easy to make it so.

It is suitable for large scale implimentations regardless of 1 or 2, it
just doesn't support 1 or 2.

I couldn't tell you, but you could take a hack at it.  I belive there
are a couple Python corba packages.
