Hi Mark,

   well, you're right, sampy just sends two parameters: sender-id (which 
is the sender application public ID) and messages.

Reading the specification you mentioned actually it seems that I should 
also send a private-key... right, but... which private-key? The receiver 
private-key? This is useless... clients know their private-key. The 
sender private-key? Absolutely no, otherwise the clients reveal their 
hub/client communication secret code. The samp.hub-id? Maybe, just to 
let the client verify that the XML-RPC call actually is performed by the 
hub and not by an intruder. Am I right?

Thank you Mark for your testing.
