Thanks for the clarification.
I am new to Python, Twisted and Zope - so I guess I look at the world
through my Perlish C++ tainted goggles :)
Just one or two comments - 30 000 feet from above. I have noticed the
introduction of Zope interfaces in other projects as well where some
developers are almost going bonkers with interfaces as "the new best
thing" and where simple inheritance is being discarded in places where
they should really be used. Don't think that is a good thing.
IMHO - interfaces should be implented on the "boundries" of a component
- i.e. those interfaces which form part of the API of a package. I get
the impression that in Zope3 they are (ab)used to try and make an
untyped language behave more like a typed language. This may work well
in an app where performance is not a major issue - but in an networking
framework the abuse of interfaces may lead to an unnecessary and
significant performance hit.
