Stan's dashboard

So I'm evaluating pbwiki for an Intranet at a company. All pages are private by default.

Now I've got a project page that I want everyone in the company to have visibility into, AND I want to give access to an outside person--a client. If I choose "custom Security" then I can restrict the page view to administrators, and then add people I want to give access to. Fine. So I add all insiders in the list, and then start to add the outside person's email.

But wait a minute! if I add the outsider to the wiki, that means they'll be able to see all the other pages in my wiki, won't they? Would I have to put in "custom security" for all the pages of my wiki to do what I want? (full visibility to all page for all insiders, but only one page for an outsider)

Seems like there should be an outsiders' security selection in addition to what's there, so you can allow specific people limited access to your wiki?

I'm evaluating PBWiki as an intranet solution. We currently have a database in which we keep lots of information, including staff contact data. Is there a way to have that information render into a PBWiki page? some sort of widget or API?
