The ICEfaces book is also mentioned in the blog of Ted Goddard (Senior Software Architect at ICEsoft). He accents that I developed a framework for the book, namely ICEfusion, to show how ICEfaces can be used.
ICEfusion and also ICEcube, the example code of the book, are distributed under the Apache 2 license. So, if you need something to demonstrate ICEfaces take the examples and adapt these to your needs for the next live presentation 
. I recommend to have a deeper look at ICEmapper, the AJAX Push game, from the ICEcube implementation.
