Rather than do that, what about recording yourself with Cheese first and save the video to a file? No need for a camcorder. Then re-run the audio and click through the slides. Then save the screencast of the slides to another video file. Finally combine both videos using gstreamer picture-in-picture compositing abilities, as explained here: http://www.oz9aec.net/index.php/gstreamer/347-more-gstreamer-tips-picture-in-picture-compositing You could probably use a video editor to do this as well.
