Not that it matters because it's too late now and it would only give us a few more months, but: Does the US government really need more than 150 million addresses, of which about half are not publically routed? Non-publically routed addresses can be reused by others as long as the stuff both users connect to doesn't overlap.
Again, I note that we've collectively allocated the 95%+ of the address space which was made available outside of DoD's original blocks, and then considering that US DoD additionally returned 2 more /8's for the community (noted here: <http://blog.icann.org/2008/02/recovering-ipv4-address-space/>), I believe they've shown significant consideration to the Internet community. The fact that any particular prefix today isn't in your particular routing table does not imply that global uniqueness isn't desired. Rather than saying 240/4 is unusable for another three years, perhaps the service provider community could make plain that this space needs to be made usable (ala http://tools.ietf.org/html/draft-fuller-240space-02 or http://tools.ietf.org/html/draft-wilson-class-e-00, etc.) on a priority basis and work with the operating system and vendor community actually to make this happen? There's a chance that it could be made usable with sufficient focus to make that happen, but it is assured not to be usable if eternally delayed because it is "too hard" to accomplish. /John (my views alone; 100% recycled electrons used in this message)
