That's all well and good. I am sure there are people like you out there that have access to tools like this - But I'm talking about publicly available tools - Ones that you don't have to be under any non disclosure agreements to use
A solution would be a tool such as the one found here and a script that spiders your website and inputs every page to the live PR checking routine, doing properly formatted output for every page. The URL that I posted is public, free and so I can show you a proof of my concept
Or you could install the seo for firefox extension and search google for site:mysite.com and get up to 100 at a time? It's just a quick scan down the page to see if any has PR.
