I ask this from a fairly clueless, out-of-date perspective, but are the current Bluetooth stacks and implementations robust enough at this point to trust? (Aside from all the higher level stuff.) P.S. I agree with what I think is the principle behind this -- I have for some time, with respect to freedom on the Internet and its like. That being that the only true security and reliability will come from owning and controlling the physical layer. I also like that, unlike with autonomous wifi access points, the signal might be able to hide -- and move about -- within a larger sea of Bluetooth connectivity and at lower powers and therefore exploitable ranges. If I'm thinking about this at all correctly (I'm unsure).
