Right - that means that instead of having a camera in whatever room Sean Patrick is in, and long stretches of dead time when he's somewhere that can't be wired for filming, you see Justin's environment all the time no matter where he is. Bandwidth also means that it can be streaming video rather than a web cam that updates every 20 seconds or so.
I'm not sure why this is supposed to be compelling. The presentation has changed, but the content hasn't. Or is it that the time is right, and there are enough voyeuristic people and enough revenue to be made from Google ads to make it worth doing?
