One point here, and it is not a big one. I don't accept that accuracy
is a sine qua non (see para 5). Contactability is, I think it ends
there. Excessive focus on accuracy of data, when that data is not
necessary any more is a cost and consumer burden, not to mention an
invasion of privacy. (eg. if I have changed my mastercard number but my
registration is paid for two years, no need to change it in the record)
I did not comment earlier on Volker's remark that responsibility for
accuracy of data rests with the registrant, but I agree whole heartedly.
How can it be otherwise? Some parties would like to authenticate every
individual and every transaction on the INternet, and see the registrars
as the entry point and therefore the logical ones to bear this
(enormous) burden. This is unnecessary and will price domains out of the
range of individuals who can benefit most from their own place on the
Internet, in my view. It would hardly be appropriate for the policy
person to point out that in any authentication scheme, identifying the
individual in the first place (prior to tying that individual to some
identifier) is a big, costly and complex matter that has slowed down
many an implementation of secure transactions. We need to limit our
attempts to identify individuals to only what is necessary.

PS I wish I had taken better notes on the whole thick/thin whois issue
during EWG. Since it took me a good while to figure out how this thing
had developed in the first place, (and many thanks to my EWG colleagues
who patiently explained it to me over and over again) I may have missed
an invitation to throw it out and discuss it again from scratch.....but
I doubt it. Anyway, we were already talking about tiered access by then
and different configurations of the model which would make it much less
relevant.
