I just read on Android Central that root access has been granted for the chromecast. Not much can be done with it at the moment though, you can just look at the files on it but I am excited to see what people can do with it. Perhaps now instead of just streaming Netflix and Youtube apps someone will just make an app that will be like a file explorer and stream apps via your phone onto your tv screen.

The article wasn't a big one on the site but it can be read here: http://www.androidcentral.com/chromecast-roo…
