This can either inherit from your existing class,

You don't actually have to do this.

No so, all you have to do is provide security assertions for them. I
usually do this is a dummy product's __init__.py.
See the examples

Yes, but you shouldn't want to ;-)

You _could_, but that's a very old, deprecated interface. And, with the
work Jim's talking about doing, it might actually stop working.
nowadays you should do:
security = ClassSecurityInfo()

Well, the thing is, the declaration that makes the method public

Brain fart, sorry. There is no allowAny in ClassSecurityInfo

Sure you can. It's usually called a python product and there are
tutorials and examples you can download from zope.org
The core principle is to inherit from one of the zope classes that you
can find in zope/lib/python/OFS such as Folder, SimpleItem or
UniqueItem.
When you do that you can save

So far I have not had any success with anything else than writing
special methods in my Classes that converts the objects to
dictionaries before passing them to the zpt or Script(Python) in
question.
But that feels like a very awkward way of doing things, and it
makeas it *very*
According to Dario Lopez-Kästen:
But in order to even display it in a zpt I must transmogrify it into a
special zope-object, and *that* is not so easy as I have discovered.
In my case I am not so interested in importing the moduels or classes
into a Script(Python) - I have allready passed
