Well as most ADSL systems in the world use PPPoA (PPP over ATM) or
PPPoE (PPP over Ethernet) I suspect that extending PPP to use IPv6
would be the simplest thing.

Actually after a quick search of the RFCs this seems to have already
been thought about (in 1998):
	http://tools.ietf.org/html/rfc2472.html

Of course this probably requires all the BT and ISP equipment to be
upgraded or reconfigured to support IPv6 (as well as the customer's
router), and I don't see much advantage to BT to do this at the
moment.
