Distributed, replicated file and data storage …
This is a project that resembles the work of the Freenet organization … only this has the backing of Microsoft! They are creating a distributed set of shared storage as a solution for fault tolerant data protection. A group of people form a “replica ring” of sorts … and begin to store files on each others file systems. There is encryption and meta-directory capabilities which make this a very likely future.

MIT Technology Review: Fault-Tolerant File Storage. That earth-shaking experience got Theimer, then an operating systems researcher at Xerox PARC, thinking about how to make computer file storage systems radically more fault tolerant. His work has helped to lead to Farsite, a fail-safe storage technology being created at Microsoft. [Tomalak’s Realm]
