[Zope] Storing a reference to a page within a python variable.

Hi all, I want to be able to store references to different pages within a dictionary in python. I know how to store the actual page(by calling it and assigning the results), but sometimes that page depends on variables that might change a few times during the course of that pages life as a dictionary value. I'm sure there is a way to do this, and I haven't figured it out yet. As an added bonus, is it possible for this reference to be useful from within python and using TAL? Thanks very much, Alec Munro
