You could also do it even better as an ADOBE Air application made with Widget Cast by Reallusion. Make a Widget that is a media player with the click link on the video to call up the client's webpage. That one would be able to float on the screen. You can add an RSS feed to it so that the presentation always has the latest info. Heck it could even load the video from the web so that you could change the video to keep it fresh, even though the customer opens up the same Air app.
