Thanks for the input.

An understandable position to take.  I'll admit I am somewhat  
skeptical that governments around the world will be willing to accept  
this approach.

I agree. Regardless of the approach ARIN takes in the lead up to run  
out, a policy proposing what should be done post run out would  
definitely be warranted.

As has been pointed out, the incremental approach of "Soft Landing"  
would allow the ARIN community to revise the policy should it be  
determined that the ARIN region is being disadvantaged.  In any  
event, I will be proposing something like "Soft Landing" to the other  
RIRs (missed the APNIC deadline, but hope to get something to RIPE  
and AfriNIC soon).

While I will admit to not having been able to spend the time to fully  
understand the "Decreasing Exponential Rationing" proposal, I do not  
believe it to be that similar to "Soft Landing".  "Soft Landing" is  
an attempt to encourage IPv6 deployment by explicitly adding  
requirements that encourage migration of infrastructure and services  
to IPv6, ultimately tying the allocation of additional IPv4 addresses  
to demonstrations of availability of IPv6 services.  "Decreasing  
Exponential Rationing" merely constrains the amount of IPv4 address  
space being allocated.  Also, I think fixed thresholds of IANA /8s  
are a lot easier for folks to understand than mathematical formula.

Again, thanks for the input.
