Trouble understanding features

Hi All,

Im curious about the limitations of mopidy but i cant find any literature explaining my exact situation.

I would like to add mopidy to my home server with a speaker connected to it. If i do this will i be able to cast via native mobile apps, ie. Tunein or Spotify (spotify connect)?

For instance i could be on the tunein radio app on my android or iphone could i press the cast button to have it stream to mopidy as i would to chromecast or sonos etc?

There is no support for either of these technologies, they are both examples of proprietary software for which no public API is available.
