Hi Alex,

    Thank you very much for having caught this definition mismatch! I 
personally see TCP/IP as a network stack on its own right. From this 
perspective, XIA, TCP/IP, RDS, and TIPC are all at the same level as you 
concluded. I don't mind adopting the definitions that are more common 
among kernel developers.

    Linux XIA is not replacing the other protocols (using your 
definition). Linux XIA is another protocol, and, as you correctly 
pointed out: a framework for other protocols.
