You are right that it is a challenge to get the support in the providers, but note that changes in the mail client are required anyway. Sure, changing the client and changing the DNS infrastructure are two different kind of beasts, but we probably can not do without the providers completely if we want ubiquitous support. > I'm thinking more of things like DHT, Distributed Hash Tables, in BitTorrent, > or > similar concepts in other peer-to-peer networks.

Just use a P2P network for all of DNS. See what happened? I just turned it around. :) The paper notes how we can utilize DNSSEC to strengthen our trust model. Similarly, we can utilize a P2P based DNS system. Now instead of one problem, we got two :) P2P systems are tricky to get right, and have their own tradeoffs. Also, while acceptance for our proposal among service providers will be tough to get, I'd expect that getting acceptance for a P2P based system would be even harder. A lot of things have to fall into place to make a P2P network a viable alternative, and not all of them are technical.
