Hi HN,
this is Jakub, founder of Estimote, Inc. (YC S13).
We just released a new beacon firmware supporting low-power routed mesh over BLE.
It's slightly different implementation that the one Bluetooth SIG has just standarized, but it will give you a good overview what is possible with Bluetooth Mesh.
If you have beacons already just upgrade the firmware and here is a nice tutorial: https://developer.estimote.com/managing-beacons/mesh-at-scal...
Feel free to post any questions - happy to answer them here.
