This is an interesting idea that I can see using in a classroom. With the success of such apps like Pokemon Go, I can see students enjoying the idea of locating and accessing information. I agree with your idea of creating tester groups amongst teachers allowing early adopters the benefit of trying a new product while gaining valuable feedback. Also your background with apple lends credibility to this idea as you can bring knowledge from both sides of the table.
The only issue I have comes from what new learning this is bringing to a classroom I cant accessing through a website. I understand the beacons use during field trips and out of class experiences however In a classroom if a student has a device could they not simply look up a coding website?
If I were investing I would likely hold off until you came back after testing in the schools.
