This sounds like it will fail in numerous circumstances where text is shown without full parsing: * action=edit * action=raw * Special:Export * diff * text in Special:Newpages RSS feed * diff in Special:Recentchanges RSS feed * Search text extracts
and probably more.
In general, I strongly recommend against trying to hack in 'access restrictions' to MediaWiki. If you *need* them, you will likely end up with a very insecure system which will FAIL you. If you *don't* need them, then why bother?
If you *need* access restrictions, I recommend that you use some software which supports this explicitly. Don't just use MediaWiki because it sounds neat or it's the first wiki you saw; you should only use it if it's actually appropriate for your needs.
