-In addition to the functionality of Tahoe-LAFS itself, a crop of related
-projects have sprung up to extend it and to integrate it into operating
-systems and applications. These include frontends for Windows,
-Macintosh, JavaScript, and iPhone, and plugins for duplicity, bzr,
-Hadoop, and TiddlyWiki, and more. See the Related Projects page on the
-wiki [3].

WHAT IS IT GOOD FOR?
-With Tahoe-LAFS, you can distribute your filesystem across a set of
-servers, such that if some of them fail or even turn out to be
-malicious, the entire filesystem continues to be available. You can
-share your files with other users, using a simple and flexible access
-control scheme.

-We believe that the combination of erasure coding, strong encryption,
-Free/Open Source Software and careful engineering make Tahoe-LAFS safer
-than RAID, removable drive, tape, on-line backup or other Cloud storage
-systems.

-Special acknowledgment goes to Brian Warner, whose superb engineering
-skills and dedication are primarily responsible for the Tahoe
-implementation, and significantly responsible for the Tahoe design as
-well, not to mention most of the docs and tests. Tahoe-LAFS wouldn't
-exist without him.

-P.S. Just kidding about that acronym. "LAFS" actually stands for
-"Lightweight Authorization File System". Or possibly for
-"Least-Authority File System". There is no truth to the rumour that it
-actually stands for "Long-lived Axe-tolerant File System".
