I'm not sure it's all that helpful to ask me to re-justify the entire NRPM.
 That requirement, in a more strict form, is what is present in the NRPM

I'm proposing to take one step toward liberalizing policy in the direction
you seem to favor.  If you're proposing that we move further, it would be
helpful if you could provide an argument for doing so.  If we can get
consensus around additional changes, I'd be happy to do so, but I don't
want to risk the perfect becoming the enemy of "better than things are
today", so I'll be most receptive to tweaks that don't completely do away
with needs assessment just yet (as that has proven very controversial to

This is a distinction that long pre-dated my involvement with ARIN.  I
think the original rationale was that, since ISPs are basing their requests
on existing subscriber counts for the most part, they should usually
justify their needs based on existing usage, rather than projections.
 End-user needs tend to be more based on deployment of new equipment, etc.
so such backward-looking needs assessment makes less sense.

What do you think ARIN should be using (other than current IP usage) to
evaluate the needs of new and growing ISPs?

I believe that, by making it easier for operators of all sorts to qualify
to receive space from ARIN, either from the free pool or via transfer, this
proposal allows ARIN to meet the needs of operators it can't serve directly
today, and to continue meeting the needs of new entrants and smaller
operators as IPv4 becomes increasingly scarce.  I'm open to suggestions for
how to better achieve that.
