Subject[resend take 1] [0/3] Distributed storage release.
I am pleased to announce distributed storage (DST) project release,
which is a resend of the previous documentation update one with
whitespace cleanups. As old tradition, this release has the new name.

DST is a block layer network device, which among others has following

* Kernel-side client and server. No need for any special tools for
data processing (like special userspace applications) except
for configuration.
* Bullet-proof memory allocations via memory pools for all temporary
objects (transaction and so on).
* Zero-copy sending (except header) if supported by device
using sendpage().
* Failover recovery in case of broken link
(reconnection if remote node is down).
* Full transaction support (resending of the failed transactions
on timeout of after reconnect to failed node).
* Dynamically resizeable pool of threads used for data receiving
and crypto processing.
* Initial autoconfiguration. Ability to extend it with additional
attributes if needed.
* Support for any kind of network media (not limited to tcp or inet
protocols) higher MAC layer (socket layer). Out of the box
kernel-side IPv6 support (needs to extend configuration utility,
check how it was done in POHMELFS [1]).
* Security attributes for local export nodes (list of allowed to
connect addresses with permissions).
* Ability to use any supported cryptographically strong checksums.
Ability to encrypt data channel.
* Keepalive messages to detect failed nodes early.

One can grab sources (various configuration examples can be found
in 'userspace' dir) from archive, or via kernel and userspace GIT trees.

Consider for inclusion.
Thank you.
