Yeah, I mostly agree... IMO, a ULA (equivalent to RFC1918, so 192.168.x.x and so forth) is the only sane way to set up your IPv6 network at home, unless you're one of the wizards who owns their own prefix. Dynamic prefix delegation just breaks too many things when the prefix changes, and I really wish NPTv6 was more supported and ubiquitous, because it solves the problem in the most elegant way IMO.

Uh, what? What do you think ::ffff:1.2.3.4 is?

huh, i was NOT aware of that. NICE!
now applications (including DNS/NAT) have to support it
i also forgot something (but not against your comment):
* there needs to be guidelines how applications should differentiate between used ipadresses (link, site, global and so on)
You don't need NPTv6 to use ULA. Just use both ULA and the dynamic prefix from your ISP. The latter is handled automatically by DHCPv6-PD, and if you're only using it for outbound connections then it changing isn't going to break anything.
I'd say this is actually elegant, compared to NPTv6 which is a kludge and will break things (and isn't well-supported anyway).
