Jeff Brenman makes the best presentations!
Jeff Brenman put this presentation together for Yugma. Jeff has a keen sense for clear simple expression. He did a great job capturing the shift that is happening in the web conferencing space, and the unique advantages that Yugma provides to users. Fact is that people need tools that are super easy to use, can be used on the fly... in an impromptu fashion. Flip though his deck at Slideshare (slideshare.net)...
