Cool! I was wondering how long it would take for someone to put something together after the SDK came out. Answer: not long!<p>Question: is this 1) transcoding like "cast this tab" does (assuming not), 2) routing the original data stream via my computer, or 3) having the Chromecast download the stream directly?<p>And if #3, are there any issues with login permissions, cookies, etc. not being present on the Chromecast?
