title: socket.io emit specific transports
body: <p>can socket.io emit in one transport style then in another?</p>
  
  <pre><code>socket.emit('my event',{data:'something'},{transports: ['websocket','xhr-polling']});
  socket.emit('my event',{data:'somethingelse'},{transports: ['flashsocket']});
  </code></pre>
  
  <p>my reason is that i want to create a flex .swf with FlashSocket.IO that talks to my server app.js the same as my client.html  javascript does.  </p>
