I'm willing to drop the triangle shape. I'm not that attached to it. However, we need to have two different devices that can be one. Don't worry about loosing them. I've figured that out. We are going to put 2 separate beacons in it. Netizens is the creator of the first beacons working in mesh network (take a look http://eonbeacon.com/), which is good for navigation as well. We are going to have an excellent tracking service within a Velo app, better than Tile.
