Raph Koster (MMO designer and expert at Massively Multiuser stuff) a rough vision for what this type of tech is probably intended for. He discusses it briefly towards the end of his (VERY strongly recommended!) talk "Still Logged In: What AR and VR Can Learn from MMOs"[1]. His essay "How to build the scary future today"[2] goes into more detail.

The overly simplistic TL;DR is: the people currently trying to track everything you do online would really love a future where all your offline physical stuff had a unique serial number and regularly updated room/gps/etc location data. An indoor map of logical features would be a useful component in that future.

I'm sure there are other, more beneficial uses as well. All technology is dual use. To understand the full impact of a proposed technology, as Raph Koster advised[1], "Every feature must be looked at as a weapon."
