What do you really want? Secure namespaces or the fun of installing
multiple wikis?

If you look into secure namespaces, you may look into Extension Lockup,
which I tried and was very satisfied.

It depends on the security level you want to achieve. By design,
MediaWiki is not build for this and can not be regarded hack proof.

Consider this to be the "Private:" namespace, plus an associateed "Private_Talk:" namespace for discussion pages.

Since in wiki B the namespace is not configured, the search will not
list any results. All database operations require a namespace as key.

If you have Mynamespace:MyArticle in Wiki A, the article will be in the
namespace Mynamespace. If you create the same article in Wiki B, it will
be an article in the main namespace, called Mynamespace:MyArticle. Thus,
even if a user guesses the right name of a protected article, all he can
do is create a new one, which is stored differently in the database.

Why don't you just try it out? you basically need to copy the whole
sourcefiles of your current wiki, change the script position in the
localsettings and comment out or create the extra namespace.
