I have not seen this messenger in action but I suggest you submit a request to add this to our application recogniztion. Please use the link http://www.paloaltonetworks.com/researchcenter/submit-an-application/ to submit the request. The application team will then take a look at the application to investigate it.
You might also get in contact with your local reseller or SE who might be able to help you in between.
