Hi, This is just a comment but not objection to the discussion, About the difference between host and router,Wiki may also be taken as a reference, http://en.wikipedia.org/wiki/Host_(network) Yes, there are software routers, the configuration option in Linux PCs and others...
but the operation of *pure host* and router are different practice. Regards Xiangsong----- Original Message ----- From: "William Herrin" <bill at herrin.us>

MIF's charter is not IPv6 specific and the distinction you draw was not made for IPv4. 2. Both the IPv4 and IPv6 network stacks for PC's and routers have stayed more or less converged for quite a while. Higher end routers have some hardware assists that don't tend to show up in PCs but they're otherwise just close to identical. If we're to recommend that change, we ought to have better reasoning than, "we didn't want to deal with the router case" and we should very thoroughly explain that reasoning.
