wondering, have people deployed IPv6-only residential

<div>Softbank (Japan) launched an IPv4-over-IPv6 service in
August 2012. They use what looks to me to be an
IPv4-in-IPv6 tunnel, but could be just a particular case
of MAP-E with no portset. The service is up to 1G down /
1G up and they do encapsulation in hardware in a
proprietary CPE.</div>

I remember them deploying 6rd, but I could be wrong. <br>
<br>
We're considering MAP or lw4o6. The problem is that our management
prefers "proven" solutions (i.e deployed by other ISPs) and the only
proven solutions I'm aware of are full blown CGN solutions. That's
why I was trying to find commercially deployed cases based on either
MAP or lw4o6. Alternatively, It would also be of value if I could
prove that, for example, DS-lite is not being deployed either :)<br>
