[ppml] IPv4 Soft Landing - Discussion and Support/Non-Support Requested

As you suggest, I think that there are implication of some policies in others.

While I usually don't particpate very much in 
policy discussions, this issue is of a great 
importance for the future of the RIR's system, so, I will make an exception.
My view is that we need some kind of  "soft 
landing" proposal, but we face two probable problems.

1) The current IANA-RIRs  IPv4 allocation 
policies works in a way in which as much IPv4 
addresses an RIR allcocate to their 
custumers/members, as much IPv4 addresses they 
can receive from IANA. So, to apply this kind of 
policies in one region would probably put that 
region in disadvantage in relation to the other 
regions. So, the first problem is that a policy 
like this probably would not be adopted only in 
one region. The challenge is coordination. 
Coordination means from my perspective to have a 
cross-regional dialogue in order to analyze the 
pertinence of promotint some kind of "soft 
landing" proposals in every region. (not 
necessarily the same policy in every region, but 
based in the same concept/objective)

2)  As you pointed out, there is a relation 
between soft landing proposal and the other 
proposals that are being discussed. (distribution 
of the last part of the free IPv4 pool)
But, IMHO the relation is the opposite of what 
you mentioned. Since the distribution of the last 
part of the IPv4 pool will naturally take off 
pressure from the unallocated pool and will help 
to avoid a competition for that pool, it probably 
will create a better environment to implement "soft landing" policies.

I will submit a proposal to all the RIRs' lists 
in order to address what I identify as the first 
problem, but it should not be considered as an 
opposition to the David's proposal.
