% Good points, though the "without recourse" is not so. Several have

% at the moment, and my position is to let them make a proposal to the list 
% as to what and when they intend to do. Let's wait to see what folks say.

% Thanks,

	cleaning up the 6bone delegations is a noble and worthwhile
	effort, however the effect of just "abandoning in place"
	is almost simpler.  If it was up to me, I'd stop doing delegations
	in the 3ffe:: space for the next 10 years. Then set up an 
	periodic/quarterly "check", perhaps with the normal cidr reports to see
	which prefixes are still being used/announced.  Encourage the
	RIRs to "remind" requestors of IPv6 space that they should 
	withdraw 3ffe:: entries when the 2001:: entries are being used.
	Follow up in four/five years and fine out why there are still 3ffe::
	prefixes in use.

	Persuade those that hold 3ffe:: space to consider moving the
	3ffe:: addresses to only those delegations/assignments that reflect
	IPv6 tunnels over IPv4 infrastructure. (a pet project of mine)

	wrt other choices, here are a couple:

		2002:: space
		"glbly unique" site locals
		link-local
		RIR - 2001:: space
		

	It is my humble opinon that its not worth the amount of effort that
	is being spent to kill off folk using 3ffe:: space. That energy could
	be better spent in other ways.
