Hi, I do not know whether this is even feasible with the given possibilities.
But it would be a real cool feature in my eyes to have the ability of streaming the same (audio) content to different DLNA and/or Chromecast Devices in different rooms.
That would give you the ability of a cheap multiroom audiosystem.
I know that it is "theoretically" makeable with DLNA (Look here for an example: http://forum.xbmc.org/showthread.php?tid=78431)
I think most developers won't implement it because you have a different delay and therefore asynchronous Music playback on different devices with different Hard- and Software.
But maybe you could make it possible to integrate a way to adjust the music sync manually for different devices?
As I said. Would be a realy realy cool feature IMHO
What did the rest of you guys think about that?
I'm realy interested in your opinion
