This works great!  Thanks!  But I see that there is something else wrong wi=
th my plan.  When I try to call MyClass.getData(self, ...), I get an error =
essentially saying that my ZMyClass instance is not an instance of MyClass,=
 so I can't call that method.  Python's isinstance tells me that this is th=
e case even though issubclass verifies that ZMyClass is a subclass of MyCla=
ss.  Is it not possible to wrap regular  Python classes with Zope wrappers =
simply by inheriting from the regular class and a Zope class like Folder/Si=
mpleItem?
