Re:For Privacy and Security, Use Public Keys Everywhere

I believe that this is what projects like Bitmessage are trying to solve. There are a few ways to go about this. One is to give everyone your message. To me, this seems inefficient, since not everyone wants your message. Another option is to use mix networks and distributed hashing, like Tor or Freenet. I suspect that something more useful and efficient could be created using rateless erasure forward error correction codes.

I would like to point out BitMessage uses streams. Streams are a collection of nodes that have a particular part of their address in common. If you have an address that is part of one of these streams, your computer will listen into that stream. So you won't download all streams keys and messages, only those that pertain to you.
