This is all correct. However, none of the factual accuracy of the above statements may prevent an aggressive and/or unethical registrar from pressuring domain owners to "protect" their name by buying IDN versions. Such "marketing" may suggest implied threats that if you don't try to buy a name of similar maening (or similar phoenetic sound) in another language the owners of IDNs may come after *you*.
Okay. I think most westerners would be shocked at some of the tactics aggressive Chinese registrars would use to get someone to register a domain name.
The answers to these questions may seem evident to people here, but not IMO to the general public. And I certainly see the fear and confusion that may accompany IDNs being exploited by unethical people. Informing the public of the issues about IDNs, reduicing fear and fraud, are what I see to be the main issues here.
To be certain, many questions and fears about IDNs will come not from new users, but from longtime users who are used to an all-latin-alphabet Internet and will be surprised (and maybe even scared) of unrecognizable names.
I am not sure, however, if these are the same as Joly's concerns.
Fair enough. Let me know how I can contribute :-) -James Seng
