[Zope] Maybe a stupid newbie question - forcing an in loop to the Root Folder's context.

I've created a method in the root folder that basically does some dtml-in looping over objectValues. It works fine when included (via var) in other methods and docs in the root window. The problem is that I want it to be aquired by sub-folders, but want it to still loop through the root folder's contents. In other words, I should be able to call my method anywhere in sub-folders or items deep in the site, and still get a list of objects in the root folder. Can I do this in DTML? Does it require python? Does it need to be an external script? Can someone point me in a direction? - Jim dongle@home.com
