Sounds great... I'd love to break into a house like that!

Maybe his wife is a florist?

Brilliant setup. Make people buy your goods and then have them donate those goods back to you. Double profit... :-O

You can run dhcp on ipv6. Your isp can choose how they set up things, just like with ipv4.

Autoconfiguration with MAC addresses might not be the answer for ISP networks, since an ISP might not have enough control about people's NICs or how they will use MAC numbers. I suspect they will offer two solutions: one DHCP-like with 1 ip for cheaper accounts, and one with /64 subnetting for more expensive accounts.

In 2000, I had an ISP that had native ipv6 support, and I was assigned one random ipv6 address through dhcp.

As I understand it, one of the main selling points of the whole ipv6 setup was that end-users would be alotted a /64 to enable them to connect more smart appliances without the hack of NATed networks (although I wish ignorant end-users would be forced to put their windows disasters behind a NAT firewall)... So personally, I would like to have a fixed /64 and use the internet as it was meant to be, with direct access to my machines at home.
