Barry has very accurately described my need as well.  We also have a multi-brand experience and restrict help center content based on user attributes of which products they have.  We need a single article to be accessible under multiple categories/sections based on what a user is permitted to see.  In addition, as others have described, we have content that applies in multiple categories as well as would like to have it available under both so users can find it no matter which one they look in.

+1 from me also.  Reusability of content is key when you have products that cross over customer segments.
