[ppml] Policy Proposal: IPv4 Soft Landing (version 2.0)

[Scott Leibrand]

As mentioned before, I support the IPv4 Soft Landing proposal.  I would 
agree with David that:

    * The IPv4 Soft Landing proposal will not significantly impair
      networks' ability to obtain IPv4 space.
    * The proposal will encourage/require adoption of IPv6 where
      appropriate, thereby reducing demand for remaining IPv4 space.
    * The IPv4 Soft Landing proposal and the Decreasing Exponential
      Rationing proposal are sufficiently different that they should
      remain separate proposals.  I believe that they are somewhat
      complementary/orthogonal, in that either or both could be approved
      independently, depending on how we want to manage the IPv4 runout
      phase.
