	Well, I know of at least two ISPs which have started serious (I mean,
	not hobby-for-researcher type) IPv6 connectivity services.  I hope
	more ISPs to follow.

	IPv6 has chicken-and-egg problem I think:
	- ISP will not deploy it until big-router-company ships it
	- big-router-company will not ship it until ISP plans to deploy
	- even if customer asks ISP, most of ISP do not care
	I really hope IPv6 in *BSD to break this rather bad loop.

	Yup, IPv4 multihoming (using portable address) does not work well with
	aggregation-oriented address allocation like IPv4 CIDR blocks and
	whole IPv6 space.  There are couple of proposals in IETF ipng/ngtrans,
	which I love to test it and hear more opinions/comments.
