Matthias Wessendorf and I had a session “What’s cool in Apache MyFaces?” in JavaOne 2010, San Francisco.
Here are the slides : http://www.slideshare.net/aliok/whats-cool-in-apache-myfaces
Html5 demo is deployed on Google App Engine : http://bit.ly/myfaces-html5-j1-demo

It was really fun and valuable for me.
