So much of what you say is driven by what the NTIA wants and what the ICANN board wants.
Guru:
I am sorry to have to point this out, but Alan Greenberg is not an employee of the U.S. Department of Commerce, has not been designated as their agent in this
process, and thus is in no better position to tell us what NTIA wants or what it will accept than you are or I am. The NTIA has told us its requirements in its public announcements.
