The "Electronic Mail Forwarders Guild" is not made of mind readers, they are capable of error. You assume that a operator would appear to be untrustworthy. I think that is a poor assumption. As an example, I have been talking to John Perry quite a bit lately, he has been of great help to me, his heart seems to be in the right place, he is certainly militant enough about remailer secutiry. I am not at all convinced that he has not been compromised (nothing personal John). It simply does not require that good an actor. If a TLA wished to infiltrate us, the traitor would seem very trustworthy, gung ho, and paranoid. I think that the odds of the "Electronic Mail Forwarders Guild" choosing a compromised Spoon-E Issuer is much greater than the odds that all members of some subset of my choosing have been compromised. The system you proposed is interesting, and worthy of discussion, but I will not actually use any system where I must put identifying information in each packet. There are ways of implementing postage which do not require this compromise. Blind signed tokens is one method. Having the user pay the first remailer, with remailers charging each other a reduced rate for forwarding is another. You make no mention of my scheme for making your system completely secure (I think). It should not be too difficult to implement, given the software you would already need for Spoon-Es. -------------------------------------------------- Lance Cottrell who does not speak for CASS/UCSD loki(a)nately.ucsd.edu PGP 2.6 key available by finger or server.

CARNEGIE MELLON PORNO NOT
by lee.noon＠mgmtsys.com 17 Dec '03

Sex in Cyberspace Now Turning University Into Cyber-Vice Cop By HENRY CUTTER Associated Press Writer PITTSBURGH - In a case that has colleges taking another look at their legal responsibilities in cyberspace, Carnegie Mellon University has blocked access to bulletin boards that students can use to call up dirty pictures. About 300 students protested the move earlier this month as an assault on academic freedom, and a public interest group for computer users suggested Carnegie Mellon overreacted. "It is censorship," said Declan McCullagh, student body president. "We have obscene books in our library, but the University isn't burning them. The university is burning cyberbooks." Carnegie Mellon officials said they fear the school can be prosecuted for distributing pornography to minors if it knowingly allows access to the pictures via the Internet to anyone under 18. Most of the schools students are adults, but children as young as elementary-school age also use the university's computer networks. The dispute started when Martin Rimm, a research associate working on a study of pornography in cyberspace, used Carnegie Mellon computers to collect 917,000 pictures, ranging from simple nudity to pictures of men and women having sex with animals. He tracked how often the pictures had been downloaded, or called up by a computer user -- 6.4 million times. When Rimm took his findings to the administration, Carnegie Mellon could no longer claim ignorance about the material, said Erwin Steinberg, vice provost for education. "It's a difficult issue, an emotional issue," said William Arms, Carnegie Mellon's vice president for computing services. He received calls from six other schools after the problem came to light. "People want to know which way to go," he said. The school decided to block access to both written and photographic pornography. In the face of student opposition, Carnegie Mellon decided not to enforce the block on text. But X-rated pictures remain off limits. "I have not accessed that material, but I feel that each person has a right to choose what kind of shoes, what kind of ties, what kind of information they want," said Cesar Rios, a graduate student in public management. Freshman Jessica Rhodes disagreed. "We sort of have to abide by the laws of the state," she said. "There are other ways of getting pornography. If people want pornography that bad, they should go buy it themselves." Mike Godwin, a lawyer for the Washington-based Electronic Frontier Foundation said the chances of Carnegie Mellon being held liable for carrying the pictures are extremely slim. Richard Goldberg, an Allegheny County deputy district attorney said it would be very difficult to prosecute Carnegie Mellon, for the same reason it is hard to prosecute other kinds of obscenity cases: The prosecutor would have to prove the material has no redeeming social value. "Then you have the problem of where do you prosecute them? Where is it coming from?" he said. Goldberg was referring to the question of what community standards should be applied to obscenity-in- cyberspace cases. * 1st 2.00b #3833 *
