        allocations are based on:

        ) current policy
        ) demonstrated need

        always have (even pre-ARIN, pre-RIR) ... when the policy was "there is
        a network and host split" then every qualified applicant got a /8.
        and your point about getting "enough" for a 12-24 month need backs
        up my assertion that you are allocated more than you need.

        there is some "padding" for you to grow into.  which you may or may not
        do. strict needs based allocation would give you -exactly- what you need
        at the time of the request - sort of like a DHCP assignment no?

        the tricky parts there are:

        ) how is utilization defined?
        ) how to accomodate historical and legacy delegations that had different
          assignment rules than are currently in effect.
        ) is it -worth- the cost to effectively manage a resource pool or are we
          willing to unilterally declare a "chernobyl Zone of Alienation" around 
          the IPv4 pool that we have, by our own unwillingness, agreed to consider
          "toxic" and too costly to manage...  and proceed to use the exact same
          policies/procedures on the IPv6 pool - which despite zelots claims to
          the contrary - is finite and we stand a very real chance of screwing it
          up too.   I'd like to see the community work toward a real 80% utiliztion
          of the IPv4 pool (since I know for a fact taht there is lots of sparse
          allocation out there...)

Just saying.
