Thanks for the answers. 
The question was about using bluetooth audio and linux experiences.

The main question was, how can I play multiple BT receiver from a linux 
machine. Anybody done this ?

On my further research BT-audio is not multicast per se and so I asume the 
sender have to manage many connection in parallel, MacOS-X user reported 
sucess, so I thought linux can do also but it didnt find a solution until now, 
... maybe many dongles.

...  it is not about audio quality, nor mono or stereo or delays very much ...  
its about using  e.g. (here) BK8000 modules  for EUR 5,70 for DIY  speaker 
which  can receive Audio (stereo) and control some GPIOs,  (also they have 
quite good audio quality) ... also its not about stereo or mono, the stereo 
was my first attempt, I want autonomous solar powered speaker of any kind as an 
loudspeaker orchestra or acousmatic, like french artists name this...  outside 
in nature. ...
