Hi knitti!

__getattribute__ could be good (I test it and I like the way if there 
are anyone with a better one)

Now my question is:

There are any way to distinguish when the property is called by ZMI or 
FTP or another "system" call (about Zope) from the property when is 
called outside ZMI?

Now I have a property like:

object.Property1 = '[/some/path]'

with the __getattribute__ override I can do

print object.Property1

and the result is ok (the result of /some/path) but now if I go to 
property tab of the object I can't see ['/some/path'] or raise an error 
telling Property1 is not a member

What I would like to create is an object that in the ZMI has some 
property values but when this properties are called the returns the 
execution of the path (like macro expansion or similar)

Is this possible to do?
