do a petstore - A petstore is a very good tutorial and demo app showing media handling, authentication, sessions and db-topics. Many developers (if not all:) already know its "business blueprint" so they/we can concentrate on the specifics of the framework and compare it to others.
I particularly like what Ugo Cei did with CHS. It demos Cocoon Flow&Forms/Spring/Hibernate. Here are some numbers: 17 model classes 7 dao classes 1 flowscript as controller with 23 actions/views 4 cocoon forms and 7 other templates.
