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.

If you want to go on a wild goose chase, start chasing down 240/4 and
you might make some progress.

As i have mentioned before, it was only after i gave up on 240/4 for
private network numbering that i really earnestly took on IPv6-only as
a strategy.  Seeing 240/4 actually work would be nice, but i have
already concluded it does not fit my exhaustion timeline given how
many edge devices will never support it.

If i have to fork lift, it should be for ipv6.
