RE: MP3 decoder packaged with XMMS
There is no cost to Xiph for copying me on these. Jack and Monty are
well aware of the legal environment in which they are operating. Please
do not feel that it is necessary to remove me from this.

That's entirely consistent with my (much less informed) understanding
of the history. It would be very interesting to know whether the
statement at http://ballsome.org/index.php/news/100 reflects their
present policy, and if so whether it would offer some degree of
equitable-estoppel-based safe harbor for distributors who can
demonstrate substantial non-infringing uses as a defense against
contributory infringement. There's no shame, and potentially much
advantage, in providing cross-conversion tools between a genuinely
free format and the current market leader.

Can you point me to a brief but technical summary of some of the Ogg
Vorbis codecs? I would be curious to compare them against the MP3
techniques, about which I know at least a little bit.

That's understandable. Any chance you could at least identify which
patent warranted a formal opinion?

Can you enlarge at all on your approach to "duty of due care"? I have
only recently run across Knorr-Bremse and am ignorant of how this
works in practice when the patents are flying thick and fast.

Absolutely it speaks volumes on the risk management front. But
Microsoft, for instance, pays out rather frequently to settle IP
suits, sometimes for reasons only peripherally related to their
validity; and I don't think watching what the big boys do counts as

That's why I put you to the trouble of commenting; I thought
debian-legal needed a little injection of educated opinion from
someone with a first-hand clue. Common knowledge seems to fade as
rapidly as common sense.

I hope I haven't put you to any trouble or expense by copying Mr.
Rosedale; some people prefer to have their legal counsel copied on
such issues when they list contact information on a page like
http://www.xiph.org/contact/ . I've added Mr. Montgomery on this
follow-up; please drop Mr. Rosedale if it's not necessary for him to

Thank you again for responding quickly and intelligently. You and
Xiph.org have my best wishes.
