For me this isn't just about ISP-forced customer renumberings, but to also 
handle power outages, equipment malfunction (so you lose your lease), 
equipment change, ISP change, and all other things that today will make 
you change the IPv4 address a few times a year or something.

I believe we should use SHIM6, MP-TCP, "mosh" and other similar techniques 
to make sure that we can move sessions around when doing renumbering.

IPv6 has the infrastructure on L3 to handle renumbering gracefully, now we 
just need L4 and applications to get with the program as well. I would 
really like to see us go in the way of IP addresses not being the single 
anchorpoint of all communication, we need to make sure that we have other 
mechanisms such as L4 protocols being "agile" when it comes to IP address 
change over time, and also having DNS or other mechanism being able to be 
updated with information over time to enable this mobility.
