I recently demonstrated at Athcon, a new security conference taking place in Athens - Greece, a new stealthy port scanning attack that is made possible by abusing XMPP. The technique uses a "zombie" host (that can be anyone in your [most probably fake] friend/contact list) and some timing calculations in order to conduct a portscan through that proxy to any target. The IP address is never revealed to the scanned victim, the same way the famous idle/zombie scan, discovered by antirez, works. The idea, a proof of concept pidgin patch and a detailed analysis can be read in the paper. You can find the whitepaper here: http://sock-raw.org/papers/abusing_network_protocols and the presentation slides: http://sock-raw.org/papers/anp_presentation.pdf It is interesting to see how protocols like seemingly "innocent" protocols like XMPP can still be abused to do things like the above attack.
