True, and a packet filter defaulting to blocking incoming traffic (like a lot of IPv6 routers do) has the same net effect, without the NAT ugliness.

Good point. Anyone got the figures for how many /56 prefixes are available? All the estimates of abailable address space focus on single addresses, but really, /64s should be considered in these analyses, because that's effectively the smallest (convenient) LAN segment intended to be assigned.

That's why I'd like some more relevant figures, taking into account current allocation practices (e.g. /56 per resifential customer, /64 minimum subnet allocation).
