I thought we were all trying to discourage NAT in IPv6.
You/we are... Which is why you really need PD, and cpe needs to be able to hand out /64s on request to downstream devices. Not surprisingly that will drive subnetting in the home. presently, plugging in more gateway/router devices results in multiple layers of nat and huge amounts of unnecessary complexity in the home network.
Clearly, NAT solves the problem ... while introducing 1000 new ones. :-/
Sure, we don't have a reasonable mechanism for ipv4 devices to pull address space out of thin air. We do have one in ipv6. This is a problem that equipment makers (as much as randy hates them) will have to address. It doesn't take much imagination to figure out how they will address it given a lack of alternatives.
