I found that using socket.broadcast.emit() will only broadcast to the current "connection", but io.sockets.emit will broadcast to all the clients. here the server is listening to "two connections", which are exactlly 2 socket namespaces

io.of('/namespace').on('connection', function(){
    socket.broadcast.emit("hello");
});
io.of('/other namespace').on('connection',function(){/*...*/});

i have try to use io.sockets.emit() in one namespace but it was received by the client in the other namespace. however socket.broadcast.emit() will just broadcast the current socket namespace.
