[arin-ppml] uncoordinated market for IPv4 addresses will cause routing failure

let's not forget the folk slicing and dicing to /24s to compete with
others accidentally announcing their prefix.  why i mention this is
because, in the long run, we can actually do something about this,
routing security.

and a new factor we will see down the road which we don't really have
today.  it falls under multi-homing, but the more extreme end of the
sport.  folk are gonna need small bits of ipv4 space to front nats,
whether ipv4 or ipv6 is behind them.  i suspect that five years from now
we could see pressure to have /27s or whatever globally routed.
providing for this was one of the ideas behind apnic prop-062, see
