[Zope] Pretend folders

What I want is to be able to pretend that a certain folder exists when it doesn't. From a database of directory structures I would like to be able to build up fake folders that don't exist. So instead of http://host/directory?dir_id=345 I would like to have http://host/directory/Business/Entertainment/Music How do I go abouts doing this? --- Outgoing mail is certified Virus Free.
