Initiatives like this is why I'm a hardcore proponent of keeping the services encapsulated, indirected, modular and flexible, ie, not tie core to any given technology or assumptions about data storage configuration. <BR>

All<BR>> of the source code is available under a choice of two Free Software,<BR>> Open Source licences.<BR>> <BR>> This filesystem is encrypted and distributed over multiple peers in<BR>> such a way it continues to function even when some of the peers are<BR>> unavailable, malfunctioning, or malicious.<BR>> <BR>> Here is the one-page explanation of the security and fault-tolerance<BR>> properties that it offers:<BR>> <BR>> http://allmydata.org/source/tahoe/trunk/docs/about.html<BR>> <BR>> This is the successor to v1.2, which was released July 21, 2008 [1].<BR>> This is a major new release, adding a repairer, an efficient backup<BR>> command, support for large files, an (S)FTP server, and much more.<BR>> <BR>> See the NEWS file [2] and the known_issues.txt file [3] for more<BR>> information.<BR>> <BR>> In addition to the many new features of Tahoe itself, a crop of related<BR>> projects have sprung up, including Tahoe frontends for Windows and<BR>> Macintosh, two front-ends written in JavaScript, a Tahoe plugin for<BR>> duplicity, a Tahoe plugin for TiddlyWiki, a project to create a new<BR>> backup tool, CIFS/SMB integration, an iPhone app, and three incomplete<BR>> Tahoe frontends for FUSE. See Related Projects on the wiki: [4].<BR>> <BR>> <BR>> COMPATIBILITY<BR>> <BR>> The version 1 branch of Tahoe is the basis of the consumer backup<BR>> product from Allmydata, Inc. -- http://allmydata.com .<BR>> <BR>> Tahoe v1.3 is fully compatible with the version 1 branch of Tahoe.<BR>> Files written by v1.3 clients can be read by clients of all versions<BR>> back to v1.0 unless the file is too large -- files greater than about<BR>> 12 GiB (depending on the configuration) can't be read by older clients.<BR>> v1.3 clients can read files produced by clients of all versions since<BR>> v1.0. v1.3 servers can serve clients of all versions back to v1.0 and<BR>> v1.3 clients can use servers of all versions back to v1.0 (but can't<BR>> upload large files to them).<BR>> <BR>> This is the fourth release in the version 1 series. We believe that<BR>> this version of Tahoe is stable enough to rely on as a permanent store<BR>> of valuable data. The version 1 branch of Tahoe will be actively<BR>> supported and maintained for the forseeable future, and future versions<BR>> of Tahoe will retain the ability to read files and directories produced<BR>> by Tahoe v1 for the forseeable future.<BR>> <BR>> <BR>> WHAT IS IT GOOD FOR?<BR>> <BR>> With Tahoe, you can distribute your filesystem across a set of<BR>> computers, such that if some of the computers fail or turn out to be<BR>> malicious, the entire filesystem continues to be available, thanks to<BR>> the remaining computers. You can also share your files with other<BR>> users, using a simple and flexible access control scheme.<BR>> <BR>> Because this software is new, we do not categorically recommend it as<BR>> the sole repository of data which is extremely confidential or<BR>> precious. However, we believe that erasure coding, strong encryption,<BR>> Free/Open Source Software and careful engineering make Tahoe safer than<BR>> common alternatives, such as RAID, removable drive, tape, or "on-line<BR>> storage" or "Cloud storage" systems.<BR>> <BR>> This software comes with extensive unit tests [5], and there are no<BR>> known security flaws which would compromise confidentiality or data<BR>> integrity. (For all currently known issues please see the<BR>> known_issues.txt file [2].)<BR>> <BR>> This release of Tahoe is suitable for the "friendnet" use case [6] --<BR>> it is easy to create a filesystem spread over the computers of you and<BR>> your friends so that you can share disk space and files.<BR>> <BR>> <BR>> LICENCE<BR>> <BR>> You may use this package under the GNU General Public License, version<BR>> 2 or, at your option, any later version.
