Using HTML5 Channel Messaging with Web Intents to create persistent relations

Hi,

I wanted to text creating a message channel between a Client page and a Service page when running in Chrome and using the JS shim from webintents.org but I didn't get it working. I a probably doing something stupid...

The code in the Client page is:

         var channel = new MessageChannel();

          var intent = new Intent();
          intent.action = "http://webintents.org/view";
          intent.type = "video/*";
          intent.data = channel.port2;

          window.navigator.startActivity(intent, function (intentData) {
              alert (intentData);
          });

         channel.port1.onmessage = function (evt) {
                alert (evt.data);
          };

The Service page code is:

     If (!!window.intent) {

          var port = intent.data;

          if (port) {
             port.start();
             port.postMessage("Port received");
          }, false);

      }

However, Chrome does not recognize port as a Message port object. What's wrong. Sorry for not being very experienced with JavaScript.
