Is there an easy way to hide a space (navigation, search, what's new)

Hi- I think I need something like a space preference that allows certain spaces to be "hidden" in places where their existence would show. My usual configuration is: public-topic-space public-topic-space limited-or-private-space I can already set roles that control who can _use_ the private space, but I often want it to be _completely invisible_ to public users. This includes: - Navigation panels - Search results - "What's New" pages - Everything else This is for when a virtual xwiki is overkill, but some spaces should not appear at all in any way other than to users who have the rights. -Tom -- May 4, 1970: Alison Krause, Jeffrey Miller, Sandra Scheuer, William Schroeder.
