I was just thinking today about how cool it would be if I could easily deploy an email service that was entirely under my control. I've allowed MS and Google full access to my email only because I don't know how to setup an email server with appropriate spam filtering and reliable security. I have my own RSS aggregation server and I don't ever have to worry about it going away as a service.

Brian K. Vaughan's The Private Eye [1] was on my mind when I was thinking about an individual being entirely in control of all their data without compromising on functionality or usability.
