[ppml] IPv4 "Up For Grabs" proposal

I can't tell if you are just eliciting feedback on an idea, or you want to 
make this into a formal policy proposal?   Policy proposals should be 
submitted to policy at arin.net - there is a template designed
in a way to help to capture the answers to important questions about why
the policy should be considered/implemented 
http://www.arin.net/policy/irpep_template.html   After a policy proposal 
is submitted it is posted to ppml and passed to the AC.  There is a whole 
process (http://www.arin.net/policy/irpep.html) but if you would like 
some help with a policy proposal, I or any member of the AC would be glad 
to help.

  If you just want some feedback.. I can do that too:

1) What is the goal of this policy?

2) Policy term?  temporary, permanent, renewable? (would be hard to undo, 
if people start using it..)

WRT the goal of the policy - this seems to reclaim some legacy space to 
create more 'private' address space, that is, address space that is not 
globally unique.

If the goal is to be able to recover legacy address space, because of 
impending IPv4 depletion, and to be able to extend the life of IPv4 - this 
isn't going to get you far.  If the space is 'up for grabs and usable by 
any organization' - you are essentially creating more RFC1918 like space. 
The point of having registered address space, is so that you know who is 
using it, and it remains globally unique, which is often important when 
you start connecting networks together, and most commonly when you want to 
route it in the "global internet"

If OTOH, you want to create more RFC1918/IANA reserved address space, my 
question to you would be, do we need it?

If OTOH, you want to scare legacy folks into signing an RSA.. again my 
question would be why? and there might be better ways to go about this.
