Do not think anyone has built such a cool tool, so this is a valid idea. If you want to do it yourself I think you might be able to do this with something like this: http://msdn.microsoft.com/en-us/library/aa302295.aspx
Everything you have in PMS can be returned to you by asking for the XML file that your PMS happily gives you. Sit down in front of your PMS machine and type in this in your browser:
http://localhost:32400/library/sections/1/all
That will give you all the movies for that PMS (if section 1 is your movie section of course). Simply change the number close to the end to see the entries in your other sections.
