Governments should not attempt to restrict anonymity. Communities should develop their own policies on anonymity. Users should know the conditions under which they are communicating. Users should know that there are no guarantees of perfect anonymity. Users should be educated about the kinds of technologies available for surveillance and for anonymity.
Anonymity requires strong encryption without government backdoors.
At least one other group decided that the government should limit anonymity. His comments foreshadow a debate similar to the one currently happening over encryption, in which the FBI insists you only use software to which the government has backdoor access. Look for Louis Freeh to demand that anonymous remailers to keep logs for his G-Men. Not only were the Federalist Papers published anonymously, but a recent Supreme Court ruling reaffirmed the right to speak anonymously. Then there are the problems of banning overseas remailers.
