The title of the meeting is "Internet Searching and the Domain Name System: Technical Alternatives and Policy Implications".
It seems to me that sans removal of intellectual property supremacy from the domain name space, well-meaning people will spend years trying to invent and tweak Technical Alternatives to satisfy an insatiable entity.
I imagine this would be fine with the IPers, who can peer over their glasses periodically to see that we remain engrossed in our technical busy work, while they write, judge and jury more and more internet-usurping rules in their favor.
Its IP Policy that is driving technical issues. Seen in that light, discussing technical alternatives becomes a meaningless exercise.
Legislate IP rights back into some level of balance and perspective relative to the internet and other interests. Then discussion of technical innovation and policy implications, based on a level playing field, becomes useful.
