Thanks Ted,

I have spoken to lots of lawyers about this and to be honest they were
pretty much clueless since the real issues involve definitions about what
technologies are covered in the user space exemptions and which are not,
and your conclusions seem right on the money.   I was advised to ask the
copyright holders their opinions, since this is very much a subjective
determination based upon knowledge of technologies and where the line are
drawn.  The legal issues are well understood -- the definitions on which
technologies are classified as user space vs. kernel and which enjoy the
exemptions and which do not are very much at the discretion of the
copyright holders.

You have eloquently answered the question.  FUSE drivers are under the GPL
and are off limits unless you plan to open source them.  Distributors
linking against Linux also sound like they are off limits too.  Given the
response, Windows Executables installed and linked by a customer are not
prohibited nor is the use of any other consumer of Linux (which is what
the lawyers have told me).

Thanks for the clarification.    I moved this thread to the FUSE list, but
to be honest, it sounds like FUSE is not the way to go.    Free BSD sounds
like the way to go moving forward for these areas.

Thanks,

Jeff
