No, won't be necessary. Typical leases on v4 are extremely stable. I
see no reason why they should be less so -- bar implementation hickups
-- in v6. My "dynamic" v4 address of my Telia DSL at home has been the
same for over a year. The ISP that messes this up will lose customers. 

As long  as we use self-healing reasonably abstracted means of pointing
out where our stuff is we'll easily survive renumbering should it
occur. As long as the renumbering is less frequent than the TTL on the
DNS records. For DLNA-like stuff, there is always FE80::/10, besides. 

        The uniqueness of the unicast IP address is the key to its 
        value and the means with which it enables us to build new 
        stuff from which we make money. Corrupting the uniqueness
        requirement is devaluing the real reach and power of the IP 
        address in search of shortsighted futile "gains" and is 
        a practice any network professional should abstain from.
