What I mean is that *if* the availability of /48 networks was an issue
for some ISPs, I'd be fine with less because I don't plan to deploy 64k
networks at home, though I already have ~9 around the firewall and don't
expect to go much further.

In fact the IoT trend could play a role here by letting users know that
they can remotely access their fridge and whatever stupid device they've
deployed. But the reality is the opposite : some gateway services are/will
be offered at a paid price to make these devices remotely accessible, and
the claimed security provided by this gateway will be presented as a real
benefit compared to the risks of anyone directly accessing your private
life over IPv6. So I'm not getting much hopes for the future in this area
either.
