Identity and the Digital Estate (via Doc Searls) -- "In this article, I will present a frame of reference for thinking about Digital Identity Applications, called the Digital Estate. I will first describe what future Digital Identity applications will look like and how they will be built. I will then show how this generalized framework emerges as a natural evolution from existing specialized, legacy Digital Identity applications - E-Mail, Instant Messaging, and Personal Home Pages. Lastly, I will describe the emergent ecosystem of the Digital Estate and why the Estate metaphor is appropriate." (Comments: I can't believe how huch Doc Searls posts each day.)
