There were messages here some time back about systems like anonymizer but chainable and using cryptography. Did anything come of that? Efficient anonymous web browsing could be a killer app for crypto. Use anonymous web access to get to hotmail accounts like this one and you have anonymous email, easy to use.
Anonymous web browsing is definitely being worked on. However, simply chaining proxies ala remailer chains is not sufficient because traffic analysis is fairly trivial. The question is what's the threat model. If the goal is to prevent the server from identifying the client given limited resources, then www.anonymizer.com or similar is sufficient. However, the real problem is preventing an entity with unlimited resources and control over most of the nodes in the anonymous network from conducting successful traffic analysis. This is an entirely different and very difficult problem. The cpunks are getting some help in this from the Naval Research Lab (although actually I think we're helping them not vice versa) because the military seems to want to be able to browse anonymously too.
