I've recently found that The Roku Channel is available to watch on platforms other than Roku, such as Android and web browsers. I've also recently gotten my hands on the new Google Chromecast with Google TV, which runs a skinned version of the Android TV OS, but could not find The Roku Channel available for it in the Play Store. Given that The Roku Channel is available for the Amazon Fire TV and Samsung Smart TVs, I don't think it's too much to ask for The Roku Channel to be ported to Android TV as well.
