title: Have two instances of a Chrome Cast App connect to the same session
body: <p>I'm trying to reproduce some of the features found in the Tic-Tac-Toe sample, but instead using the Chrome Cast API. Does anyone know how to connect multiple devices running Chrome and the Cast extension to a single Cast session?</p>
  
  <p>The only documented (somewhat) way of connecting is using the <code>api.launch</code> method, and when that is called from the second device it re-opens the receiver page which reloads all the content (disconnecting the first device).</p>
  
  <p>I've also tried creating a new connection by POST-ing to http://:8008/connection/, which gives me back a WebSocket URL. When I try to connect a WebSocket to that ws:// URL, I get a "Unexpected response code: 408" and am unable to connect.</p>
