mGreg--
Funny you ask this question, it was one of the first I asked when I started AVS.
Basically, it varies between systems, on what they consider to be exclusive.
In practice, exclusive is considered a seperate door-way to the members area of your AVS site.
so,
sex-key-index.html sex-key-join.html
sitepass-index.html sitepass-join.html
etc...
and a common members area should do the trick.
Just don't try to promote each mirror with the same link lists.
