I'm in the same situation. 🤔 I surfed across the code and the only thing would be to be able to somehow tell other servers to search for the socket with a given ID and not emit the message to it.

I think you should be able to achieve what you want with except():

io.except(socket.id).emit(/* ... */);

io.to("room1").except(socket.id).emit(/* ... */);
