Yeah, we need an architectural solution.  Maybe complete seperation of
locator and ID???

Large ISPs have been accused of liking the provider lock-in too...  I
personally am no in that camp.  I think IPv6 needs an architectural
approach to solving PI and and multi-homing.  If we could completely
seperate locator and ID with something like 8+8/GSE, have DNS only reflect
the ID, and have the network map one or more routing goops to a site (Yes
I know this needs some protocol), and use only the low order bits for TCP
session termination and firewall filters.  Then we have solved both the
provider independant and multi-homing problem.
