Those are great. Other favourites from the list are:
1) The Pynchon Gate: A Secure Method of Pseudonymous Mail Retrieval
2) Mixminion: Design of a Type III Anonymous Remailer Protocol
3) On the Economics of Anonymity
The third in particular is interesting, because it analyzes the social roadblocks to deploying decentralized systems. Everyone knows that decentralized systems are technically challenging, but very few people consider the issue of actually incentivizing people to contribute to your network once you get it working, until it's too late.
