No, I don't want to dictate, it's the opposite, I say what _I_ consider
fair use. Other people will consider it other ways. It's exactly the
gray area Linus was talking about. As long as all parties agree on one
given fair use, there's no problem. Discussion and sometimes litigation
is needed when some parties disagree.

100% agreed with you on this !

Ted, I think you get me wrong. I don't want to dictate anyone what's
derived work and what is not. Instead, it's the opposite. I just want
to indicate them what's explicitly permitted by the author and copyright
owner (at least by me as the author/copyright owner when I can) so that
people can decide by themselves what level of risk they take by doing
whatever they want. What I consider the most important is to encourage
fair use even in areas I never anticipated, and when possible, try to
protect fair users from the GPL zealots who want to bite whenever one
gives them an opportunity to abuse the gray area to feel stronger.

I have opened even more my software and tried to clarify the reasons
why I chose the dual license exactly for this reason.

What I was suggesting is to add a clarification with the kernel to
avoid those overly long threads on LKML such as this one. It would
basically be structured like this :

"Use in the following order" :
  1) fully respect the license and you're OK.
  2) play in the gray area if you need and if you consider it fair use,
     but seek legal advice from a lawyer (and not LKML) before !
  3) explicitly violate the license, and prepare to get sued sooner or later.
  For GPL zealots : please do not report what _you_ consider abuse to LKML,
  contact the abuser, then a lawyer or specialized sites for this.

But Linus is right, he's not the only copyright owner, and that makes it
harder to touch anything related to license and use.
