Yes. That is what most ULPs will do.

Yes, the AIDs can be used for referrals since they are not really different
than today's IP addresses; they are locators.
The only thing to consider is when AID(A) isn't working as a locator when
C tries to contact it.
There are two choices:
C can detect that the locator doesn't work and do a reverse+forward DNS
lookup to get the whole locator set (Ls(A)).
The referal can include Ls(A) instead of just the AID(A); this requires
modifying existing IPv6 appication protocols which do referal.
