Most likely the customers still on dialup are not going to worry about
IPv6 - if their systems even support it. In fact several operators I
have spoken to have considered their legacy dialup plant as a good place
to test Carrier Grade NAT in a low impact manner.
Couple it with some kind of ALG (transparent proxy + DNS tricks) for
IPv6-only sites and you have something which might work.
If you really need native IPv6 support for dialup then using a legacy
NAS as a dial-terminator LAC and tunneling to an IPv6 capable LNS might
be a solution for you.
