Right- I feel a Raspberry Pi and a bluetooth module (or a handful of them) would be a lot cheaper. Set it up to repeatedly ping everything in range, stick it to a battery pack, and just go about your business. It would certainly illustrate some of the many shortcomings of Bluetooth, and always-listening services. I'm not advocating that you should, keep in mind. It certainly seems to be in poor taste, but there may be a platform for using it educationally, I.e. hacker cons.
