So what is MetaKit lacking?  I think
perhaps I'm not following some of the
flurry of posts in this thread.

*That*'s an interesting usage profile!
Let's return to this later; perhaps we
can generate still other ideas for you.

One mystery to me:  why doesn't DB2 get
more attention?  Version 6 has large
objects, user-defined types, user-defined
functions, triggers, and is available at
no charge for Linux.  I'm just astounded
that this hasn't created more of a buzz.
I'm bring it up here because, with all
the Version 6 goodies, IBM has taken to
talking about its "object-relational"
capabilities and "support for object
orientation".  It might suit your needs
to host DB2 on a Linux box, and leave
just the client software on your MacOS
desktops.  If I didn't have MetaKit, I'd
probably go in a much different direc-
tion and see how nicely Python and DB2
can play together.
