While I think the points above are great I think to tie it all together
the use cases would be of major importance.

My view would be explain basic functionality in 'x' chapter's including
concepts, tools and reasons.  Have use case scenario's to 'paint a
picture' of how to extend one's basic knowledge to examples of what is
capable of being done with selinux.  (Max seems to have a lot of those
and I think that talking to him will be integral)

It does help a lot thanks for the feedback.  Should we take the FAQ and
amalgamate it into this guide, it will use information from the FAQ
anyway.  What is left over can be created as a FAQ of this guide?

Cheers,
