There are a few different possible approaches to take, the simplest
would probably be to use Ceph omap directly, which is documented at:
http://docs.ceph.com/docs/master/rados/api/librados/

Locking and transactions would need to be layered atop this, possibly via
a separate Samba Object Class[1] running on the Ceph OSDs.

All theoretical at this stage unfortunately, but I hope to get some time
to work on it in the future.
