[Zope] Find a user's UserFolder?

Does anybody know a recipe to find out, given a user object and a context object, the acl_users folder in which that user lives? i think i could cook something up with aq_inner and aq_parent but i'd first like to know if there's a canonical way to do this. -- Paul Winkler http://www.slinkp.com Look!
