I doubt that they have the resources to engage someone else. My
is that lawyers do not work for free, they charge their clients
on a time and materials basis. Therefore, if the client (ARIN BoT and
do not ask ARIN's counsel to look into the possibility that these
plans are stepping into the area regulated by the SEC, then they won't 
engage someone to look into that.

So far, from the discussion that I have seen, it does not appear that
anyone seriously considered the possibility that the IP address
market proposals are getting rather close to the territory that the
SEC regulates. That's why I'm raising the issue here, in hopes that
some of the people on this list will discuss it with the BoT,
and with some sort of legal advisor who has expertise in the right
area of law. It could be the current counsel or some other lawyer.
That is up to the BoT.

And just what policy is that? We regularly see incidents where
organizations announce addresses into the DMZ that are not registered
to the organization. If you talk to the operational folks you will
learn that it is not a simple matter to figure out whether a 
particular route announcement is proper or not.

Tell that to the people who couldn't get to YouTube a week ago.
Now imagine what would have happened if Pakistani Telecom made
a typo and accidentally announced address space used by a
German ISP for their modem dial customers. Instead of knocking
out a high traffic site due to blocking their nameservers, 
it would cause intermittent outages to a few customers, many of 
whom would redial and solve the problem.

The fact is that there are big impact address blocks and small
impact address blocks. Not all are equal in their importance to
North American ISPs.
