Home assistant, multiple mopidy server and snapcast group (?) - how to set it up?

Hi,
I am trying to have multiroom/multizone audio with multiple mopidy servers (one for me, one for my wife).
Right now i’ve managed to have two clients working, but listening only to one (default) audio stream or to have multiple mopidy instance working, but no audio streaming.
What are the steps to get multiroom multiaudio ? Is snapcast good solution (great piece of code though !) ?
I had problem with setting (even hardcoded) two different clients each one to different stream on same network - how can i set it up ?
