As for those two scenarios (IPv6-only ISPs and IPv6-only clients, to simplify them), the document doesn't place them as first preference solutions. However, the fact is that various *extremely* large operators find themselves more or less forced into these scenarios by IPv4 exhaustion.
Some of the extremely large operators have found themselves having to deploy ipv6 extensively in order to manage CPE devices and their infrastructure networks. However, I'm not aware of any large provider which is deploying ipv6-only customer access products, either due to a shortage of ipv4 space or any other reason. If you can supply names of providers doing this, I'd be very interested to hear. That's not to say that they won't start doing this relatively shortly. And you correctly point out that we need to create solutions _now_ so that access providers will have feature equivalence when they start deploying ipv6 in anger on access / hosted networks. This is a cue to get people on this list to shout at their vendors for ipv6 feature equivalence on their favourite kit. Nick
