I can't imagine. Reality? I have been working with computers for about 10 years, and I don't even *know how* to post anonymously. I know how to find out, but I've never bothered. Never felt the need. Like most people I know. : (In the July 1992 Bulletin of the AMS, Shreeram Abhyankar says that : Peter Neumann said that William Snow Burnside, who worked on the theory : of equations, is not the same as William Burnside, who worked on the : theory of groups of finite order. Both obtained a D.Sc. from Dublin : around 1890.) Same name != Same person. We know. : > But I also see applications for secure newsgroups based on : > real world identities. : : I do not. In fact, unless you have an application which depends on the : difference between one real person with two names and two people who : happen to cooperate (overtly or secretly), an obvious isomorphism : argument shows that your application *cannot* depend on ``real world : identities.'' Except for certain government functions (such as voting) I Say what? Think of email firstly. Think of the applications for Non-repudiation, for example, that that offers. Think of EDI. Think of digital contracts. Now generalise email, and get conferencing and netnews. Why shouldn't generalised email have the same applications? : see no such applications; and those functions won't be carried out on : newsgroups any time this millenium.
