They can play the IM game too - endlessly tampering with their protocol 
a little to screw you up. Cisco would find that hard with SCCP, and 
probably wouldn't want to do it ayway. Because they run a service and 
can pump people updates its probably pretty easy for Skype.

If people don't want to play nicely in the sandpit, don't mess about 
with them. Kick 'em where it hurts. :-)
