Google’s Chromecast is very slowly growing in functionality. Following the arrival of the dongle’s SDK, users are already starting to see the benefits of what developers can do. Starting today, users further intrigued by Chromecast’s future can now participate in the Google Cast beta, which you can think of in context to Google’s regular Chrome beta updates. Google Cast beta will allow you to see what Google is working on for the dongle before it hits a mainstream audience, hence the beta tag, sort of like seeing Google Now in the Chrome beta before it’s officially available to consumers worldwide.
At the moment, there’s no immediate benefit to using the Google Cast beta extension. You can already beam content from your phone, tablet and even your browser to the Chromecast, and it’s not really clear what other features to expect. However, if you want to get in on the action, you can easily add the beta to Chrome by visiting the source link down below. Google strongly hints that the beta is meant for developers and advanced users, so definitely proceed with caution.
