I'd be interested if this revision has changed anyone's mind or answered any 
questions for anyone.

Personally, I believe this only really answered one of my questions included 
below.  I've included a few additional comments in line;

It is still unclear to me what remedy you are seeking from ARIN.  I believe 
that this has to be clarified.  I think some kind of delay is about the most I 
could personally support, a reassignment would create a very bad precedent,

Thank you, this has been clarified, five years.  But please realize that there 
are many end-users that have been using address space for five years or

I think you intend this to be ARIN Staff, but I think this still needs to be

I'm still concerned about this.

I'm still concerned about this, too

I am concerned that this sends the message that renumbering is "TO  
HARD" even for companies in the business of providing network 
infrastructure, with staffs of network professionals, especially if we were to 
allow reassignment.  If we allow CI Providers an exception from 
renumbering, how do we as an industry justify requiring most end-users to 

Below in the rational it says "interfere with the continuous and seamless 
operation of that critical infrastructure or hardship to the provider."  
Unfortunately I believe this is double speak for renumbering, unless you can 
explain how else a transfer would "interfere".

I could maybe support this if renumbering were explicitly defined and not 
interfering or creating a hardship.

I'll add another issue;

7. I believe the text also seems to put the presumption in favor of the CI 
provider, why shouldn't the CI provider have to prove harm first, rather than 
the transferee prove that the transfer is justified.

I would like to see those that support this policy address these issues.
