corolian -> WLM's signatures (13.Oct.2009 9:20:48 AM)

hey guys, I need to allow Windows Live Messenger's text chat to pass thru but block its file transfer, webcam and voice. I know the ports but that would be inefficient if MS changed its versions so i think i should go by signature. Is there any way to detect the signature of the activities or can i get them from somewhere to block them? thanks
