[pp.int.general] copyright vs. "droit d'auteur"

[Richard M Stallman]

    This could be adapted to various licensing models, with a sensible
    scale (in French we'd call it a "barème"): for instance,
    - you want the full restrictive author's right? 5 years it is.
    - you want to forbid commercial use of your work (cc-nc)? do so for 7 years.
    - you want to forbid modifications? OK, 10 years.
    - you want your work to be freely copyable/modifyable/sellable? 20 years.
    .... and so on.

This is a very interesting idea.

I think the main objection to the previous proposal for longer
copyright for free software is that that seems like an ad-hoc
exception.  With your idea, it is not ad-hoc, it is systematic
and logical.
