Synced Multi Room Audio

Hi,

i found some solutions for synced multiroom audio for the raspberry pi (max2play which uses LMS/squeezelite or an airplay solution).
But I really love to have this feature integrated in kodi.
Isn’t there a possibility to integrate the features of the xSqueeze Add-On?
Would be great to be able to play a song of the native kodi library and have the possibility just to select the player(s) where the song has to be played.

Mustn’t there be a huge interest in this?
If this is to hard to achieve, is there another way to have multiroom audio by using kodi? Maybe in combination with the chromecast players?

Thanks for Feedback.
Luigi
