Do you use time of arrival techniques? What strategy do you use to overcome indoor multi-path conditions? Are there more detailed implementation notes somewhere?

Reading the documentation, I agree that you're abstracting away the "nitty-gritty" of location-finding, but I think it'd be really helpful to see where measurement errors might be hiding via an open description of the computational model used, even if (or especially if) it's very simple. It would give me more confidence as a user and allow me to be more forgiving if there were reasonable discrepancies in measurements.

Looks really cool! I think I'd like to try this and write about my experiences.

We use combination of many different techniques incorporated into our SDK, so there is no one specific formula - think more about it as a "driver" for the physical-location and communication device (e.g. iPhone).

The major role is played by beacons. Since we manufacture them we have a full control of the entire physics behind the signal propagation. You can read more here about it: http://blog.estimote.com/post/106913675010/how-do-beacons-wo...
