Digging out an old tree-walker experiment:

This is in a ZPT named 'recurse' somewhere above whatever you want to list::
<ul>
 <li tal:repeat="item here/objectValues">
   <span tal:content="item/getId" tal:omit-tag="">An object</span> :
   <span tal:content="item/title" tal:omit-tag="">A title</span>
   <span tal:condition="python:item.meta_type=='Folder'" 
tal:content="structure item/recurse">A Folder listing</span>
 </li>
</ul>

It can be used like::

<div tal:replace="structure here/recurse">ASDF</div>

It's not DTML, I know, but you should be able to either deal with the 
ZPT or translate it, as it's not that complex. I haven't tried it on 
LocalFS, but so long as it uses objectValues to list its objects (and 
I'm pretty sure it does) everything should work fine. You may have to 
change the meta_type in the condition if LocalFS doesn't use Folder 
(though, again, I think it does.)
