Hi Enrico, Your suggestion of an embeddable kv-store backed by BooKeeper sounds nice. I don't think anyone has made open a system that does it and is production quality. Is the API of your kv-store just get, put, delete, or are you thinking of more sophisticated operations, like conditional writes, read-modify-writes, etc?
