    <li><a href="http://code.google.com/p/brackup/">Brackup</a>, my original content-addressable backup tool, but didn't store directories as the digest of their contents.  (so backup manifests were huge)</li>
  </ul>

  </ul>
  <li><a href="http://www.monotone.ca/">Monotone</a>'s "Certificates" are similar to Camli claims.</li>
