Libraries + RFID + Augmented Reality = ?

Okay, so Apple has a patent on blah-dee-blah and the next-gen-iProducts will have an RFID chip onboard, but what could this mean for libraries?

I'm not familiar with what you can do with RFID, but I was wondering if there would be an app that would be called a Dewey Killer.

I mean, if you could find the books with your phone, why would you need to catalog the books? If each thing could broadcast its location, then is there any need for authority? The books could be anywhere and still be findable.

So you hold your phone up in the library and your reality app shows you the floorplan.
Some other app filled with ISBNs or titles accesses the catalog.
Then what?
Is there a database of RFID transponder signals? What is the range of the phone's antenna?
Would the phone scan the shelves of books and pinpoint the location of the title? Assuming anyone still wants printed books in 2011.

Maybe you know the answer:
Libraries + RFID + Augmented Reality = ?

Because I'm hoping it's multiple choice so I can pick "C." When in doubt, I always pick C.
