And it should be possible for a router to request a CERT for the
addresses is it allocated by ISP A along with their assignment
and provide it to ISP B, ISP C ...  It just needs to supply
a public key for a private key it knows so the allocation process
can fill in the rest of the details and sign it.

Whether this ever gets down to residential equipement I don't know
but it would theoretically work.  There is no reason it couldn't
work.
