Oh trust me, I'm all to aware of the insecurities involved with Bluetooth. Check out this website, I have a dozen more on WarChalking if you'd like.

I imagine that some form of encryption like WEP would be in use as an option (maybe even built into the negotiation firmware on gear like headsets).
Although believe it or not even digital stuff like GSM isn't totally secure, do you think intelligence agencies would actually allow something that they couldn't decode if needed?
They might not be able to trace you to closer than the nearest Cell (in a big city that might be as narrow as three apartment buildings), but they will be able to hear what you say if they need to.
I think you're right, the BlueTooth equipment would be aware of eachother, that's what the whole hardware protocol is about. But would you actually be able to recieve and send streaming audio, without some sort of additional audio codecs?
As I said believe I'm not to sure on the finer points of bluetooth, but I know a couple of the guys in the Office have bluetooth phones, and when they go into meetings together, the phones notice each other, and even identiy the the device by the Phonebook entry if it is present.
Think of it as omni direction longer range IRDA, all compatable devices talk to each other.
And like USB, if a blue tooth device is detected by a PDA or Laptop/PC then it will identify itself just like your webcam/scanner/gamepad does, and when the OS knows what it is, it will load the device, so your bluetooth will then become another input/output speaker/mic channel
