While event schedules and scores are always available at the official Chinese Olympic site (above), I was looking for live streaming coverage of the various events from the Internet. Unfortunately, NBC's streams will not play in Europe, BBC's won't play in the Netherlands, and, while EuroSport is streaming their cable channels, 1, 2, and News for a 4.50 euro/mo. fee, it's only selections and summaries of events.
Fortunately, the European Broadcast Union is streaming live coverage of a wide selection of events on a dozen channels at no charge: open camera, competitor annotations, no commentary. It seems to require IE to run: it gave an error in Firefox. You do have to refresh the connection every 20 minutes, but the quality is excellent.
