Steve, I'm persisting a 'transitional' object through a few views, spawning descendants from it and then deleting the parent object. In this case, then, it doesn't seem to make sense to publicize a reference to the transitional object in a url because the referenced object will not be persisted indefinitely -- indeed its creation should be silent to the user.
