Using SketchFlow for Presentations

If any of you caught my Mix presentation on the Microsoft Silverlight Analytics Framework, you may have noticed that I used SketchFlow the prototyping feature in Expression Blend to present the session.  I really like SketchFlow and I thought it would be a great way to demonstrate the technology as well (I’m a big fan of Marshall McLuhan).  You can see it at https://charette.com/saf/

Has anyone else tried this?  Any suggestions?  Does it work?
