You can go to the news folder with a lot of <dtml-with> statements,
and the choose the amount of news you want to display.

<H1>News</H1>
<dtml-with xyz>
...
<dtml-with news>
<dtml-var ListLatestWeekNews>
<P>
<A HREF="<dtml-var "absolute_url()">">[News Archive...]</A>
</dtml-with>
...
</dtml-with>

You can use ZCatalog with something like (Untested):

<dtml-in "Catalog({'meta_type': 'News'})">
  <dtml-if sequence-start>
     <ul>
  </dtml-if>          

  <li>         
  <a href="<dtml-var "Catalog.getpath(data_record_id_)">">
  <dtml-if name>
  <dtml-var name><dtml-else><dtml-var id>
  </dtml-if></a>
  </li>

  <dtml-if sequence-end>
     </ul>
  </dtml-if>          
</dtml-in>

The NewsItems still need to register with the ZCatalog automatally,
which is not implemented yet. You would have to [Find Items to ZCatalog]
in the root Catalog to collect News.

Two examples:

http://zdp.zop.org:8080/ZDP/projects/zdptools

Just create a special ListProjectsEqualExposure in NewsFolder.

This can be done by adding an abstract method to the News. 
The constructor and add methods would have to be changed a little.
Just look at WebSiteLinkFolder for an implementation.
