make that an address *block* per household.

not likely - putting NAT in the path would make the household
net nearly useless (because a lot of the things for which you want 
a household net imply assigning an external address to devices
within your household) 

We are of course talking about IPv6 here - IPv4 doesn't have anywhere
nearly enough address space to give every household a single routable
address.  And NATs make no sense at all in a world where you have plenty 
of address space.

At best NAPTs trade off address bits for port number bits - and in IPv6 
port number bits are the ones that are scarce.
