It's not a tangent at all, and for almost the exact reason you cite. You would say "it can easily be done." I would say, "it can easily be enforced." I'm not seeing an effective enforcement mechanism here. Without that, I don't see how it can easily be done. Basically what you're saying is, "I don't want other people to be able to publicly share data that I feel personally identifies me." That's a perfectly understandable want, but you can't make data uncopyable. Digital information may be easily and near costlessly copied and shared: that's just its essential nature. > 3.

I don't believe 4 is the case at all. In this era of Facebook, Twitter, social media and people profligately sharing information, well... this seems a lot like locking up the barn after the cattle have run off. > "This phone number is not listed in the phone book or at directory > enquiries" is easily achieved by being ex-directory; this does not > affect the usefulness of my telephone service. You're begging the question: how does it get made ex-directory? In the case of a telephone, it's because you have a single point of authority who will enforce your wishes. In the case of the certificate servers, how does it get done? I'm not saying it shouldn't get done or that I wouldn't like it if it were done. I'm only saying that, at present, it doesn't appear it *can* be done. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
