That approach sounds good to me :-)

This is interesting with respect to Zope.

Everything in Zope is expected to have a default and/or management
interface that fits within very well-known parameters.

However, Products are also meant for combining in arbitrary ways, and a
variety of different variations of presentation -- from application
developers adding new header and footers, to rewriting index_html
methods for very different presentation, to output into various dialects
of XML, via FTP, and so on.

I can see PTK development right now going through a difficult patch
where we need to decide how to get the tightly-coupled UI and
application logic moved to a much more flexible system.

Thanks for the link. I'll refresh myself with some challenging ideas :-)
