in <> we see:

(*2)    Q: But what IS the Internet?
        A: "It's the largest equivalence class in the reflexive, transitive,
        symmetric, closure of the relationship 'can be reached by an IP
        packet from'". Seth Breidbart

by which definition, matthew's observation would be correct.  folks who want
to run V6 only and still be "on the internet" will need proxies for a long
while.  folks who want to run V6 only *today* and not have any proxies *today*
are sort of on their own -- the industry will not cater to market non-forces.
