I wanted to talk to you about something I'm thinking about. The idea is to make a small app that does direct P2P communication. Each person stores encrypted their contacts routing information. You can direct-message (server-less) if the person is online, or if not, send it encrypted to others who are online, and when the person logs in, it's routed on to them. You could do micro-blogging like this, where messages pulse out to two or three degrees of separation, and only if they are validated (i.e. liked), do they push on further. This lets spam die soon (or sooner if it's marked as such) but important messages will make their way through the system. What do you think?
