Read the chapter on the new media tags today – very interesting, and great to see that even though they’re not fully supported there’s a range of fallback options available, both built in to HTML and via JavaScript. It sounds like there’s really a lot of scripting opportunities available (or will be available!) to go with both video and audio, which makes me think that my idea of a mobile piece using <audio> and the geolocation APIs, while possibly not entirely feasible right now, may be in the near future – can’t wait!
