title: Zend ACL in models vs Zend Navigation
body: <p>I like the idea of binding ACL to models like described here:</p>
  
  <ul>
  <li><a href="http://weierophinney.net/matthew/archives/201-Applying-ACLs-to-Models.html" rel="nofollow">http://weierophinney.net/matthew/archives/201-Applying-ACLs-to-Models.html</a></li>
  </ul>
  
  <p>But how can I combine this with Zend Navigation? When rendering the sitemap, I'd have to instantiate all the models.</p>
  
  <p>Did someone actually used this approach on at least medium scale site and can share his experience on solving performance issues?</p>
