I'm reminded of ye olde Gumstix BlueSniper rifle. Back in the early 2000's there were a series of exploits against bluetooth stacks. The standard response by the industry was that they attacks weren't practically exploitable due to the low power of typical bluetooth devices.

The BlueSniper was a cantenna + gumstix SBC specifically constructed for the purpose of demonstrating the low cost of the threat.
