Unfortunately there does not seem to be a hypertext archive of the list but the post was from 2003-07-08:

I don't know how to attack the people which talk about "intermittent connected networks".
The problem I see is that people are locked into the IPv4 world where a DSL modem have one address which might change every connect. That is extrapolated into one IPv6 prefix which changes every connect.
Instead, to me, the user should get the _same_ IPv6 prefix every time he connects. As long as one connect to the same upstream network, the IPv6 prefix should not have to change. And, switching upstream network will force a switch in prefixes of course. The renumbering event comes when _connecting_, not disconnecting and connecting as the address can be kept until a new prefix is to be used.
Is this not true?
Further, we do not have a good session layer in the IETF which means a network _always_ have to reset the connections when a renumbering happens, which is the same as a more drastic network topology change happens. The solution to this is mobile IP.
What else? What's so difficult here?
