Nice thought experiment, but 99.9999% of the routers in the ARIN region (you
know, all those boxes consumers and SoHos are sitting behind) don't support
IPv6 and the vendors have shown absolutely no interest in adding it. Not in
their new products, and certainly not in the millions of old boxes out
there. And, even if it were available, how do you plan on reaching out to
millions of Joe Sixpacks and Grandmas and convince them to upgrade?
An IPv6 core is irrelevant if none of the endpoints can reach it. Vista
finally has v6 on by default, and maybe 20% of users will have upgraded by
the end of this year, but they still won't be able to reach an IPv6 router
even two hops away at their ISP.
