I made a small Cocoon web directory, long ago, and made it available free,
through CocoonWiki. (http://wiki.apache.org/cocoon/ExampleApps)
Over a period of time, I received many mails thanking me for the application.
I have to work on improving the directory application. I will work on it, once I find time.
Here are some screenshots:
