I thought we were talking about collaboration. MSN, IRC etc are 
basically chat protocols. Cerebro has little to do with such protocols; 
its goal is to provide efficient and scalable presence and data sharing 
in an ad-hoc, mobile environment where even IP addresses are a burden to 
maintain. I believe such functionality to be central to OLPC and should 
not be used "interchangeably" with anything else as long as you have and 
"msh0" interface ;-)
