Hi Reinhard,although it's a full webapplication and not a live site, it would be cool to have Mindquarry (http://www.mindquarry.com - The OpenSource Collaborative Software) listed as using Cocoon 2.2-dev on http://cocoon.zones.apache.org/daisy/cdocs/g2/g1/g1/g1/706.html.
A site permanently running mindquarry is http://www.mindquarry.org, which is our project server.
Thanks! Alex -- Alexander Klimetschek http://www.mindquarry.com
