Thanks Rico. We aim to please here at Liferay.

Regarding your question, yes ICEfaces supports JSF 2 implicit navigation. The demo you downloaded has a view named confirmation.xhtml that tests this:
1<!-- Test JSF 2 implicit navigation -->
2<ice:commandButton action="/views/portletViewMode.xhtml" value="#{i18n['submit-another-application']}" />
