Websockets can be a great solution. For instance, you can create a pub/sub design pattern where the two users will subscribe to the server via a websocket for instance . . . 

var ws = new WebSocket('ws://yourdomain.com/ws-route');
ws.onmessage = function(m) {
console.log(m); // this is how you will receive your messages
ws.send('i am acknowledging your message and sending you back mine.');
}

every send from either users will be read by the server and published back to both users (or the other user depending on your strategy). in this way, you can achieve this effect. for instance, you can hook the on keyup or something on the textarea to ws.send using the value of the textarea. then you can hook the onmessage even to change the value of textarea whenever you receive a new messsage.
