If you have friends who recommend Zope, you are probably already quite
familiar with Zope ;-)
But ... if this is about offering an alternative for the
content/run-time-configuration-space ZODB, why would you encourage putting
ZPTs and Python scripts there? Isn't that a step back to the Zope 2 days,
where content and logic got intermixed in the same database?

No, not at all. But I don't to put code or templates in the ZODB either, I
want to put them in python modules. I would like the option of storing my
content in an RDBMS more transparently, possibly via some ORM mapping like
SQLAlchemy so that it's transparent to me as the python developer. I have
no idea if it's technically feasible, but imagine how great it would be if
deriving form Persistent and configuring that particular class via some
ZCML directive as being RDMBS-stored with a given OR mapping (to map my
fields to a particular datbase schema, much like Hibernate does in the
Java world) simply made that class be stored in the RDBMS.
And I'd like to make it easier to talk to RDBMS' in Zope, although I think
libraries like SQLOS or SQLAlchemy sound like nicer paths to that end as
opposed to having Zope invent something of its own (not that I've used
either, of course, I've only read a bit). Anyway, didn't mean to hijack
However, a similar story for on-filesystem content storage would be
interesting, although that would require some sort of marshalling
technology (storing python pickles in files is not that interesting, since
it's still a black box). I suppose the WebDAV file representations of
objects that exist today would work just as well on the filesystem, though.
