Re: 6to4 deployement issues - was 6to4 security questions

Brian, 

I know it's not the best solution, but it's the best tool we currently have
to give our end nodes sitting at home on a DSL or cable modem an IPv6
address. I'd much rather have the ISPs advertise or delegate a prefix, but
realistically it won't happen because they have no incentive to make it
happen. 

In order to boot strap the process and get a wide application deployment, we
need some user perceived advantage for IPv6, and peer to peer maybe the way.
To get peer to peer to work easily, IPv6 is a good tool, but to get an IPv6
address, 6to4/Teredo seem like the only possible route at this point for a
home Mac user.

I'm not sure that the relay model will collapse if many 6to4 users are using
it, because the reality is that a 6to4 node will most likely be talking to
another 6to4 peer and will really not go through any relay for most of its
traffic. Why? because there is nothing of interest for them on the 6bone, so
that won't change much to the current situation...

The alternative, the way I see it, is just to ignore IPv6 for now and wait
for providers to wake up one day and magically start giving out IPv6
prefixes. Is that what we want?
