When you set it up and start using it. With 6to4, the chicken-and-egg 
problem seems to be gone. Isolated IPv6 networks can communicate 
transparently over IPv4 with no special per-peer configuration. 
Everybody enables 6to4 once, and it's done. As far as I can tell, IPv6 
will be widely implemented when people start using it, and they can do 
that now.

If you want native connectivity, I think the first step is probably to 
set up 6to4 then start talking to your ISP about their running a 6to4 
gateway and getting connected to the IPv6 native internet. In the mean 
time you can use the 192.88.99.1 multicast address as a default route 
for 6to4 and it'll find the nearest public 6to4-to-native gateway. You 
can also use a tunnel service provider like freenet if you like. I 
haven't found the need so far.

I'd be surprised if ISPs became interested in offering IPv6 directly to 
user endpoints any time soon - the upgrades to support it would probably 
be rather expensive, and using 6to4 over the last hop is no big deal 
anyway. Setting up a 6to4-to-native gateway on their network might not 
be so much fuss though (and they could always tunnel out if their 
upstream didn't route IPv6 natively).

I've spoken to my ISP (WestNet) a couple of times about IPv6, but 
they've given the usual (and sensible, really) response "when the demand 
is there." Demand won't exist until it's /really/ useful, and that means 
more people using it.

So help create the demand ;-)

Hmm. Final in what sense? Everybody will have IPv6 internet 
connectivity? (they do now, using 6to4, unless they're behind an 
unpleasant firewall). Eveybody will have _native_ IPv6 internet 
connectivity? Some people will be using IPv6-only internet addresses? 
The internet will be using only IPv6? Eveybody will be using IPv6-only 
addreses even on their LANs, too?

There are many possible meanings of 'final implementation'. The one I 
expect Cisco probably means is 'the majority of core Internet backbones 
and providers will support native IPv6 routing.' Or, 'The majority of 
major providers will have bought new, expensive routers from us.'
