DHCPv6 would be one option, static addressing another.
Exactly.
DHCPv6 prefix delegation to supply the /56 block, I use wide-dhcpv6-client; I then let neighbour discovery (via radvd) propagate addresses to the local LAN, which in practice means my laptop, as the other devices on the LAN are all IPv4-only equipment such as a SIP phone and a printer.
My router looks after all of that. The router is advertising a /64 prefix to the LAN. I have several IPv6 capable devices - a number of PCs, one Mac, and a handful of iPhones and iPads (yes, the iOS devices support IPv6).
My Linux machine is also serving as the router and the modem (with a Traverse Technologies ADSL card).
We'll see more of those. I also know people who would like to become informed of any IPv6-capable SIP phones on the market.
That would be handy, though the SIP gateways I use don't support IPv6 (yet).
FreeSWITCH and Asterisk both support it. I don't know of any SIP to PSTN gateway available through an ISP that does, but on the other hand, IPv6 certainly simplifies making calls to other peoples' SIP clients or FreeSWITCH/Asterisk systems (provided they have it on their networks, of course). In essence, NAT goes away.
