IBeacon in the Classroom?

I have been reading a lot about Apple' iBeacon. I know it will be the next invasion of privacy issue we will need to address, but then I thought about what it could do for us in education. My school is 1:1 iPad 3-5 grades. I imagine that if their iPads can be recognized when they come in the classroom I can assign a topic or an agenda of things to do that day for each individual student. We rotate students into different classes and I see that this can give them topics and assignments as soon as they come into their classroom. I can see the opportunity for individual questions depending on how I differentiate and the activity. I can see the opportunity to use it in the classroom. I also see it as an incentive for students to remember their iPads. Our iPads to home for home learning (after a short presentation and signing a permission form).

I know I can do many of these things with other means, but having the information come right when they enter the classroom, no matter what classroom, is exciting. If students come to a classroom  museum, a presentation can share information, help, and give suggestions on what to do. How fun would it be to have different pictures or presentations come up depending where students are in the school? What about when a parent comes into the school. Information, directions to get to the right room for a class production or school activity. 

These are a few things I see that can be used with this new technology. I wonder how long before we can set up beacons using this technology?
