ok, this kind of async communication is no problem with XMPP. We have 
packets (IQ) that expect a response. But the socket is never blocking. 
Messages expect no response at all.

You should take a look on the JO#s library page [1]. There are several 
lightweight libs in many different languages supporting all devices and OS.
