If there is no gateway somewhere with an IPv4 address, we will do very
little.

We performed this experience last month at an IPv6 training in
Nouakchott (Mauritania). The students had only IPv6 connectivity to
the Internet. As Mark Andrews said, we were not able to even resolve
the names with AAAA records because the root does not have IPv6. In
the end, we cheated by adding a DNS gateway (BIND on a machine with an
IPv4 address) and a Web gateway (Apache with mod_proxy on a machine
with an IPv4 address).
