And I just want to point out that a full /8 (worth $188,911,452.16 at the benchmark rate as set by Microsoft/NNI) is dedicated to AMPR... :-)

When I was at IANA, we (where by "we" I mean Leo Vegoda :-)) looked at trying to reclaim this /8 around the same time we were recovering the /8 dedicated to X.25.  The decentralized nature of administration of 44/8 made this somewhat intractable.  It'll be interesting to see how this plays out in the future address markets.
