title: OpenSocial gadget-to-gadget communication via gadgets.rpc
body: <p>Could I have an example of communication between two OpenSocial gadgets using the <a href="http://wiki.opensocial.org/index.php?title=Gadgets.rpc_%28v0.9%29" rel="nofollow">gadgets.rpc</a> API?</p>
  
  <p>I've searched for one, but the closest I can find is a deprecated example of gadget-to-<em>container</em> communication.</p>
