@Xathros We plan to work on triangulation once other core components of our app are fleshed out. Triangulation can get rather tricky due to the relationship between signal strength, battery power, antenna position, and dense materials in the room. It's going to be tough to develop a precise triangulation algorithm, but we're committed to doing this down the line.
For the time being (and most likely for launch) we're going to develop a probabilistic model and offer calibration controls for proximity detection.
Our eventual goal is to develop this detection well enough such that a beacon in every room isn't necessary for precise location tracking just as you're describing.
