title: Does XenDesktop expose a Push Notification service
body: <p>I have been reading the XenDesktop API looking to gather session data and found Get-BrokerSession provides the information i'm looking for.</p>
  
  <p>What i have been unable to find is a means for XenDesktop to push a message to my service when the session state changes (or any other data for that matter).</p>
  
  <p>Do you know if its just not a feature available from XenDesktop or if i have missed something in the documentation?</p>
  
  <p>Note: At present this is research and don't have a service in place.  I'm a C# developer but don't have any problems using a more suitable platform if i can get the data i want in a timely fashion.</p>
