I've been reading a lot about the need to replace email and I'm not quite sure why we're not moving to an XMPP based model. It seems rather perfect for this kind of thing: 1. Federated 2. Users are already familiar with the addressing format 3. Easy to use, could easily integrate with existing email 4. Easily piped through Tor or i2p or whatever Security could be handled by using OTR the first time users happen to be on at the same time and exchanging PGP keys automagically with some kind of validation that the user can actually understand in place. I really don't see this as incredibly hard to build. Why are we not seriously looking at it? Sure, it doesn't address meta-data (it probably could though) but it's a step away from traditional email and towards something new. Thoughts? Cypher
