Bitmessage

I found a nice application which might replace email in some time: Bitmessage.

Basically, Bitmessage creates a Peer-to-Peer network, i.e., a network of equal participants. The quite interesting feature of this app is that it broadcasts messages to (all) participants in this P2P network. As the message is encrypted with the public key of the intended receiver, only this person is able to decrypt the message. The cool feature now is that nobody knows who was able to decrypt the message. So, not only the message itself remains secret but also the identity of the receiver remains hidden. 

The drawback: it does not work on mobile devices as you constantly receive the broadcast P2P messages. The battery of the mobile device would be drained quickly and also the P2P traffic would deplete your 500MB of free traffic… The solution for this would be some kind of a client/server model. You could install a Bitmessage “server” on your home server. A client on your mobile device might connect to that server. Whenever a message is received by the server it gets pushed to the mobile device. Vice versa, the mobile device might send messages via the server. I really would like to have this kind of thing, …
