Not necessarily NAT - I see this as a good place for ISPs to step
in and provide dual-stack transition aids (web proxies, mail relays,
recursive DNS, etc., with v4 and v6 capabilities).

Interesting enough, this can be turned around - for very large networks
that are already using a proxy-only connection to "The Internet", it 
might be a workable solution to move to IPv6 internally, and use IPv4 
only on the external proxy...
