Yeah, I was following that activity, but as it's key-based Google simply revoked the keys and devices would no longer stream to it. There used to be a solution to extract the key from your own Chromecast to simply use it for your own purposes. But then they evolved the protocol to Cast_v2 which IIRC had more hardened security, so it's just a matter of time until they stopped supporting v1 and simply lock out all devices. It's a pity, because it would be great to push content to custom receivers in your house (i.e. send a YouTube link to a Squeezebox server)
