This is the most concise explanation of the problem so far.

I don't like binary security modules, and I won't use them nor
write them, because that's my desicion to make.  Whether they
are legal or not is not.  It's all there in the GPL for well
paid lawyers to determine.  It doesn't seem that there's any
benefit to adding to the existing licensing terms -- it all
boils down to which of the two above cases is true.

Ding.

I wouldn't mind any 'We heartily suggest/prefer' wording, just let's
not get into anything legal or restrictive or the license could become
internally contradictory and make it more difficult to prosecute
GPL infractions.  (Where there are two different ideas in this
group about what constitutes an infraction...)

I always assumed that the LSM was to be treated no differently than
existing modules -- LKMs may be close source.  It was never said
otherwise anywhere when this project was formed.  Changing (ahem,
clarifying) it at this stage of the game is a bad thing.

Had I been able to contribute actual code to this project
(the days never are long enough, are they) I'd have more
of a direct say.  Taking an approach like 'oh, X of Y
developers say one thing, now that we asked' is not a fair
way to make desicions.  Though many on this list have not
contributed code, they have made comments and suggestions
which were used by the primary coders.  Perhaps we should
take a grand survey of everyone and see what they think,
since they all had some input, if not output, into the
code as it stands?  No, that's even worse.

The LSM code is GPLd.  That was a stated requirement from day one.
Nothing else was.  Leave the interpretation of binary module
acceptibility/nonacceptibility to the GPL and the lawyers, that's
not our job.
