xcode iphone bluetooth chat between device

Question

I want to know if there is a framework or method/technique that will allow me to write an iphone/ipad that will allow one device to act as a "Leader" and the other devices as "Followers" in a shared book reading.

For example:

Device 1: Leader Device 2: Follower

Device 1: opens an book app and turns to page 11 Device 2: opens the same book app and automatically "follows" device 1 to page 11

This sounds like there needs to be some network communication like bluetooth.. Anyone seen this type of thing done?

This is precisely the sort of thing Game Kit's peer-to-peer connectivity was created for.
