Google fs?

Parent article: The Ceph filesystem

There's my project -- http://allmydata.org Tahoe .  It is an open source distributed
filesystem with very nice security properties -- everything is encrypted and integrity-checked
and you can share or withhold access to any subtree of the filesystem with anyone.  It uses
erasure coding so that you can choose any M between 1 and 256 and any K between 1 and M such
that the file gets spread out onto M servers, where the availability of any K of the servers
is sufficient to make the file available to you.

Regards,

Zooko

Yeah!  Also we've separately published the erasure coding library, which is derivative of
Luigi Rizzo's old library, but to which we added a Python interface, a command-line interface,
performance optimization, and other stuff.
