Note! I am only requesting support to audio output via Google Cast protocol as supported by "Chromecast Audio" reciever dongles (and not support Chromecast video output or recieving).
Why you ask? The two awesome things about Chromecast Audio dongels is that they are cheap and support grouping for multi-room syncronization over WiFi.
Google have also recently licensed its Cast technology for audio to multiple speaker manufacturers under the "Chromecast built-in", so many speakers and AV-receivers from third-parties will likley soon support Chromecast Audio without dongle.

The awesomeness of Chromecast Audio on existing devices is that any music/audio app can add support for it on iOS (iPhone/iPad/iPod) and Android as well as Google Chrome web browser to stream audio to Chromecast Audio dongles and speakers over local WiFi, including with multiroom support.

How could this be done in Domoticz? For starter a few developers from the Home Assistant project have made "PyChromecast" library as an open source Python module to talk with Chromecast, maybe someone can check it out?
PyChromecast - Library for Python 2 and 3 to communicate with the Google Chromecast (for video) and Chromecast Audio. It currently supports:
- Auto discovering connected Chromecasts on the network
- Start the default media receiver and play any online media
- Control playback of current playing media
- Implement Google Chromecast api v2
- Communicate with apps via channels
- Easily extendable to add support for unsupported namespaces
- Multi-room setups with Audio cast devices

Not sure if anyone on the Domoticz development team have got a few Chromecast Audio yet but I stongly recommend it regardless if you integrate it Domoticz or not.
I have bought a few dongles myself so far and have them connected to active (computer) speakers around the house and they work great.
These new Chromecast Audio dongles have finally brought the possibility for simple and cheap multiroom music playback to the masses!
