Here is how I have been blocking it with a little help from my proxy
vendor.

kill *.msgr.hotmail.com
kill *.messenger.hotmail.com
kill svcs.microsoft.com/svcs/mms
kill with http header content type of "x-msn-messenger"

It has been effective for me. Not all firewalls will be able to look into 
layer 7 to check the headers though. 

Thanks,
