	who is going to decide whether you are within the first 10000
	(lucky) routes, or you are outside of it and now can't advertise?

	there are other multihoming mechanisms that does not impact worldwide
	routing table size.  for example, draft-ietf-ipngwg-ipv6-2260-01.txt
	and some others.  you may want to try these.
	(but "multihoming" is rather a vague term, so the goals may be
	different by who you talk to - the goals of the above draft is
	clearly stated in the draft)
