I wrote the diagnostics for the shared registry system you guys use every time you buy a domain. I'd written these kinds of diagnostics for 20 years so it was sort of a natural.
They also sent me two three plane tickets: 3 for the remaining two IFWP meetings after our group didn't show up at the first conference partially due to lack of funding - the other reason was out belief this should be done on the net, the event was being cybercast by the then young Berkman Center for Law and Technology at Harvard University. They also bought me a plane ticket to the Berlin first ICANN meeting as they had asked me to be one of their representatives on the names council. The ICANN board instead retroactively changed the bylaws is secret and disqualified me. For this involvement I was referred to as "NSI's shill", which is of course patently false.
I only ever spoke my own opinions and in fact differed with NSI in several major areas of domain policy. But, we were both of the realization that an ICANN run by a non-elected board was a dictatorship that would make things very difficult for the people already suffering an abuse of due-internet-process because of the trademark community.
