For me, what would do it is a complete product that is not niche. A Chromecast competitor that supports the big platforms and content providers out of the box (Android/iOS, Spotify/Netflix, Alexa/Google/Siri) would be ideal. This already exists in the Chromecast, except it's not open. Ideally, it'd just be software on a Raspberry Pi or any hardware.
