With respect to my colleagues and Steve Ryan, our Counsel, if I followed
every lawyer that told me something different than I believed with regards
to issues affecting a business that I am involved with I would not be here
today.

In this case, I'm pointing out what appears to be a contradiction. How can
we say that an allocation system that provides for different fractions of
needs is _not_ ok for one party; ARIN as part of the the RIR system via the
global policy I referenced, but is ok for another; in-region networks that
are impacted in the exact same way?

I think that we've got the right idea, maximize end user access, but the
wrong method. The statement was also fairly weak in that it used phrases
like "on it's face" and "significant" and "legally unobjectionable". In
reading between the lines I think that it's to be understood that this issue
isn't completely thought out.


Best,

Martin
