   And how much operational experience is there?
   
=> the mobility stuff (use of bindings) is implemented but not yet the
router renumbering (needed to set preferred lifetimes). Of course it
needs some security (authentication) too.
Another point: this works for ISP failures, not for renumbering because
old addresses should be stiff valid (but default lifetimes are 7 and 30
days then renumbering survival is only a concern with very long connections).

PS: there already are some multihomed sites on the 6bone, operational
experience will come with router renumbering implementations.
