One thing it may allow is grabbing the private key it uses for Device Authentication and emulate a Chromecast on other devices. It would enable streaming from Chrome to anything using the Chromecast protocol. See [1]. I had a go at implementing the protocol server-side on node, so it's basically waiting for a valid cert. I couldn't test it much though it should work. See [2] and [3]. Any help welcome.
