`decryption inevitably involves copying' ? Has there been an authority saying that that's wrong yet ? Not that it matters for interoperability reasons...

I would have thought where the copying was legal for whatever reason (fair use, changing format for personal use in your walkman, time shifting, etc), then any decryption incidental to that copying would be equally lawful.

2. DeCSS contains key material to which the DVD consortium holds the copyright.

I doubt anything which is likely only 128 bits long is copyrightable. Moreover, isn't there some requirement for "artistic merit" before copyright is possible, which would exclude random numbers more-or-less by definition.

But then, Demon are well-known for having a silly legal department, as seen in the Godfrey case. Has David Swarbrick's posting access been reconnected yet ?

I think the main problem with Demon's approach is the wording of its standard letter. I am sure it could be worded in a much more conciliatory tone and still be legally watertight. Essentially, it needs to draw attention to a "possible problem" and to invite (even require) some comment from the person concerned.
