You could use Youtube or Google Video to host the files, though the resolution is limited. Google publishes a series technical video presentations series [1] this way.
For most presentations, you might only need to have an audio track sync'ed projector video. The presenter could use something like Wink [2] to record the this without any equipment. If you want higher production values, intercutting a camera shot of the presenter with the slides would be a good step. The biggest challenge could be catching audience questions on the microphone. -- Rick [1]: http://video.google.com/videosearch?q=user%3A%22Google+engEDU%22&so=1&num=20 [2]: http://www.debugmode.com/wink/ -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
