Multi-room support is really neat feature that will compete with hardware like Sonos. With Chromecast audio you can use existing speakers to create a multi-room listening experience.
I believe that is the case. I highly recommend just purchasing an RPI 2 and throwing the OSMC distro (Debian+Kodi) on it. Kodi supports the AirPlay protocol, so once you enable it in services you can use https://play.google.com/store/apps/details?id=eu.airaudio&hl... and basically pipe AUX out from your phone to multiple devices on your network. :)
This obviously requires the dependency of your phone, but I prefer the flexibility.
That sounds cool. So basically I don't need the chromecast audio if I have the PI, right?
I like the iOS' system level of audio output (AirPlay) and didn't know Android is flexible enough that an app can do that!
