Hi,
I have a python Product MyProduct, defining a class MyClass. I want
 to be able to do two things with this class from a Python Script:
- Access a property defined in the class without creating an instance
 of the class
class MyClass(SimpleItem):
        menu = ('a', 'b', 'c')
In Python Script: menu =
 context.Control_Panel.MyProduct.MyClass.MyClass.menu
- Create an instance of MyClass without doing registerClass on it.
The question is, how do I create the right permissions so the above
 can be done? I tried playing with the various methods detailed in
 PythonScripts/module_access_examples.py but didn't get anywhere.
i would do the above with some accessor functions in a Utility module of the
product and then use PythonScripts Modules allow access  utility for example.
#Utils.py
from Products.PythonScripts.Utility import allow_module
from MyModule import MyClass
allow_module('MyProduct.Utils')
def myclass_factory(*args):
     return MyClass(*args)
def myclass_attr_access(name):
      return getattr(MyClass, name, None)
in a python script
from MyProducts.Utils import myclass_attr_access
etc...

Thanks, Kapil... good suggestion. Sadly, I'm still not getting 
anywhere... I tried every combination of modules, classes, methods 
and allow_class/allow_module I could think of, and nothing works.

in Utils.py:

from Products.PythonScripts.Utility import allow_module

allow_module('MyProduct.Utils')
allow_module('Products.MyProduct.Utils')
allow_module('Control_Panel.Products.MyProduct.Utils')
    (I tried each one of the above 3)

def myclass_attr_access(name):
     return getattr(MyClass, name, None)

in Python Script:

from context.Control_Panel.Products.MyProduct.Utils import myclass_attr_access

Result:

import of "context.Control_Panel.Products.ERAA.Utils" is unauthorized

I also tried:

in __init__.py:

class Accessor:
     def myclass_attr_access(name):
     return getattr(MyClass, name, None)

allow_class(Accessor)

in Python Script:

from context.Control_Panel.Products.ERAA import Accessor

Same result. I'm stuck. Any more ideas?

TIA, Itai
