All mailbixes are actually grouped together. I have rented my apparment and i have very little control over the mail box. Its much more like federation then it is like peer-to-peer. In the modern world you have control of almost nothing. You always rely on a huge number of profiders. The importent thing is that their is competition and that if you are unhappy, you can do it yourself. Thats federation, a model that scales and has at least the potential to compete with centralised systems. Peer to peer is incredibly hard. I would love to live in your fantasyland, where NAT does not exists, everybody runs cheap linux servers that are always up to date and reachable, even of they are behind shitty ISP provided routers. If you want to spend your effort on solving these problems, more power to you. People like Gnunet are doing a fantasic job at proiding a basis for a truly peer to peer system that is secure. I prefer to deal with the reality and advocate solutions that have at least some chance of actually working. I am happy to host a number of services for my friends and familly, and I happly federate with others. I will hover defently not go out and tell my parents that they should go out and buy and run a freedom box.
