Do you have any examples of this? I was excited for this use but everything I can see suggests that it is highly inaccurate:

BLE is not ideal for accurate positioning, or RSSI for that matter. That said, it works for proximity, which should be sufficient for many applications.

This is why it's bleeding edge technology. At the moment it's not very good; and it won't be for some time. To get to something useful will probably take multiple iterations.

This is why it's so exciting. If you can build something useful with the current generation of technology; it will get better.

But you said:

"With two or more beacons in range you can triangulate for an accuracy within centimeters."

it appears that is objectively not true. In fact, the technology powering iBeacons does not seem to be capable of it. So, sure, in a few year's time, a beacon-like technology that may or may not be called iBeacons will allow for accurate positioning. So what?

I've seen a demo; it was finicky and had issues and didn't do orientation.
