Noted: Google’s Chromecast to get Android mirroring, ‘Backdrop’ slideshows and casting from nearby devices via The Next Web
Later this year, Google will update Chromecast so that anyone can choose and control the content being streamed on the device – even if they’re not on the same Wi-Fi network as the tiny dongle.
Essentially, Chromecast owners will be able to authenticate users in the nearby area. This means that if they’re on a cellular network – either because they can’t be bothered to type in a Wi-Fi password, or because you just don’t trust them with it – they can still access the Chromecast.
