Yes, well if the authentication can be sorted out this would be much
better than having to mess around with a registrar's crappy web interface.
Authoritative nameservers could automatically ensure that their glue is in
sync.

It's likely that if you have fairly static connectivity you can leave
longish TTLS in your DNS, on the knowledge that if there is an outage
things will come back with the same setup as before. This will work for
multihoming but not mobility.

However this requires that higher level protocols have good connection
setup code that can try multiple paths concurrently (so you don't have to
wait for a timeout if one is down) and good failover support (SCTP?).
