The "Upspin" global filesystem

A group of Google developers has announcedthe release of (an early version of) a new global filesystem called"Upspin". "Upspin looks a bit like a global file system, but itsreal contribution is a set of interfaces, protocols, and components fromwhich an information management system can be built, with properties suchas security and access control suited to a modern, networked world. Upspinis not an 'app' or a web service, but rather a suite of softwarecomponents, intended to run in the network and on devices connected to it,that together provide a secure, modern information storage and sharingnetwork."
