Lazyweb query: CloudStore (or KosmosFS)

Does anyone have any experience with CloudStore, formerly known as KosmosFS? From http://en.wikipedia.org/wiki/CloudStore:

CloudStore (KFS, previously Kosmosfs) is Kosmix's C++ implementation of
Google File System. ... CloudStore supports incremental scalability,
replication, checksumming for data integrity, client side fail-over and access
from C++, Java and Python.

The project site is here: http://kosmosfs.sourceforge.net/

I'd be interested in comments on general usability, quality, and "feel"...

thanks!

My impression is that HDFS has at least one and maybe two orders of
magnitude more users shaking the bugs out.  So if I needed a GFS clone
I would use that one.    Also, if I needed to use the source I'd much
rather read someone else's Java than C++.

hey Jonathan, thanks -- GFS advertised differently so I didn't think
it would fit my needs, but it does seem to in actuality.  It's pretty
usable from Python?

Sorry, that would be HDFS :)

Dunno, but I would think that between the Jython, Thrift, and libhdfs
options something probably works.  It looks like third-party SWIG and
ctypes wrappers for libhdfs are out there.    The command line is
pretty complete, too: <a href="http://hadoop.apache.org/common/docs/cu
