Adrian;
I'm just think about routing table size - allowing customers to multi-home (and perferably load balance over both of their links) - and am not really worrying about IP space conservation. ie. basically thinking in an IPv6 world.
So, global routing table size should be <<10K.
If the customer wants to change either provider they need to re-number - which is not nice.
It could be possible for ISP A to break, still announce the large special block and not have access to either the customer or ISP B - in which case ISP A could be blackholing the customer's data for some parts of the Internet - again not nice ;-(
Oh, yeah, it requires someone to use ipv6 ;-)
A serious problem is that there are many tuples of ISPs. Masataka Ohta
