title: Publish Subscribe from WCF to Android, Iphone, WP7
body: <p>Is there a framework that supports publishing (pushing) messages from a WCF service (REST or SOAP) to various clients like IPhone, Android and WP7?  I'm thinking I can use the WSDualHttpBinding to do dual communication between WCF and WP7.  However, I'm assuming WSDualHttpBinding is not supported in the other two platforms since is not a WS-* standard and there's a lot of stuff that WCF does to establish a receiving channel on the client side.  Is there any other way to accomplish this? How would I about rolling my own?  </p>
  
  <p>I'm thinking about exposing my WCF service as a restful endpoint and implement a COMET style pub/sub and calling it good.</p>
  
  <p>I'm stuck.  Any help would be greatly appreciated.</p>
