That didn't do it, but it did prompt me to go re-read "Acquisition
Algebra" which is always a good time.  :-)

It seems like what I want is exactly what aq_inner() is supposed to
do... return an object wrapped by containment only.  But for some reason
it's still not working with any combination of aq_base and/or aq_inner.

Anyway, I settled on a workaround for now... for methods I'm going to
wrap this way, I stuff the name of the container into
REQUEST['traverse_from'] and add this code to the aliased methods:

<dtml-if traverse_from>
   <dtml-call "REQUEST.set('me', restrictedTraverse(traverse_from))">
<dtml-else>
   <dtml-call "REQUEST.set('me', this())">
</dtml-if>

And then call everything from the "me" object, ex:

<dtml-var "me.getId()">


Seems to work fine, though I'm sure it's not as efficient as it could
be.

Thanks for your help.
