If I'm not mistaken the proposal removes the 3 month and returns to a 12 
month needs assessment after the RIPE free pool is exhausted, because of 
various dependencies on that policy, like their transfer policy and LIR 
assignments to end-users.  ARiN's polices are structured differently and 
don't have the same dependencies.  Our equilivant to RIPE's soft landing 
policy originally excluded transfers to begin with, and end user 
assignments have by ISPs have their own separate language.

ARIN has chose a different way to handle run out than APNIC and RIPE, 
they both have fairly equilivant last /8 policies.  We ARIN chose to go 
a different way with we are essentially treating the 3/4 or the last /8 
the same way as the rest of our resources, without something like the 
last /8 policies that APNIC and RIPE have I'm comfortable maintaining 
the 3 month window.  The reality is that APNIC still has a free pool, 
they are just handing it out on completely different rules, we choose 
not to go that route.

Honestly, I think it is to late to change the way we are going to run 
out now, we should stick with the plan, now one know which way is right 
or wrong.  Honestly if it was totally up to me I would have done things 
a little differently.  But, I'm comfortable with the plan as we have it, 
everyone just needs to hold on for the ride.
