Yeah. I think it was only a matter of time before this happened, hit it myself the other day.
Right now the plugin is too simple for your setup. It functions in two ways: 1) where it acts as a general, site-wide disclaimer and 2) the shortcode force display that shows for every single page view with that shortcode.
It sounds like you need a combination of that - you have 4 pages that need protection so you use the shortcode, but you only want to have to click through once for all of those pages... right?
This is totally feasible, but it's gonna take a bit of plugin tweaking. It'll be a much-needed feature though!
Here's the problem: jquery.cookie.js accepts a 'path' parameter that determines the location of the cookie. By default it's set to the entire site, or "/". What we need to do is specify paths for a set of pages, or have grouped disclaimers that watch for their own $_COOKIE variables.
1) do you have any programming/development experience?
2) when do you need this done by?
