Use independent channels with backup plans

On August 17, 2002 I gave a keynote speech at the 1st International Conference on Web-based Learning (ICWL 2002) that was held in Hong Kong, using a combination of telephone, Internet presentation (web pages in HTML format) and video (using NetMeeting). International calls are getting cheaper and the telephone call is only 5.7 cents a minute from USA to Hong Kong. With the above setup, to deliver the 60 minute keynote costs less than 4 US dollars. Notice the backup plans.
