Indeed, that does sound simple. Obtaining such a commitment may prove to be 
a little more difficult, since it permanently encumbers use of one or more 
address blocks.  I am happy to ask, however, if there is a strong level of 
support to do so.  Alternatively, there is valid contact information listed 
in WHOIS for US DOD and other commercial /8 address block holders if you 
wish to ask one directly.

p.s. Considering that we've collectively allocated the 95%+ of the address 
     space which was made available outside of DoD's original blocks, and 
     the DoD additionally returned 2 more /8's for the community (noted here: 
      <http://blog.icann.org/2008/02/recovering-ipv4-address-space/>), they 
     may actually have a different perspective us coming back to impair some
     of the remaining space they still hold.  I'm happy to discuss it, but 
     wanted to point out the long history and potential different perspective.
