Currently, most residential customers have PA+NATv4, where the CPE provides the public IPv4 address to the NATv4 box 
(which might be the same box as the CPE) via DHCP (or PPPoE). As such, all internal devices are shielded from all 
renumbering events.  In a NATless PA world, all devices will need to be renumbered on a change of provider.  While in 
theory, address lifetimes and multiple addresses should reduce the impact renumbering might have, I will admit some 
skepticism that renumbering IPv6 providers will be sufficiently transparent as customers are used to with IPv4 
PA+NATv4. Perhaps I am wrong.
