Provided your classes are true Python classes and not types
(implemented in "C"), then you do not need proxying but can
use a so called "monkey patch" to add the security declarations
at startup time to your classes.

Search "zope.org" for "monkey patch".

You could use dynamic proxying (something what "ExtensionClass"
and "Acquisition" does) but you probably do not want to do this.
