Dissent – Accountable anonymous group communication
Some paper reading shows that while interesting, the technique being used has issues with churn. This means small, reliable groups can use a tool like this. Anonymity is only provided within the group! You cannot hide your membership. In such a situation, anonymity is only improved by making the group larger and because their solution cannot handle churn, it will not scale larger.<p>In general anonymity and scalability seem to be at odds, so this is not surprising. A breakthrough showing this to be the case would be awesome but (I think) unlikely.
