Today, I would like to make the following (maybe closing) words before somebody says I would block a development: 1. In general, there is a copyright for every protectable work done by a person in the moment of its publication, but in practice it is hard to prove, specifically in such a technical case. I will not go into the legal details. Said this, at least I reject my claims, but still think that generally it would by a constructive measure if even ideas are referenced in relation with open source hard- and software. In my case it led to the situation that I have stopped to publicate ideas, with some very few exceptions. 2. In particular respectively from the point of view of the software design, the implementation is virtually what I have proposed (as well). Indeed, there are some interesting details and elegant paraphrases. 3. I think it would be interesting to analyze how well this FS works respectively to compare this FS with databases that implement something surprisingly similar. C.S.
