I wasn't disbelieving, at least not on that kind of level.

That's what I was getting at; the device *does* see all communications, but 
unless there is a method to flip on the equivalent of ethernet's promiscuous 
mode, you'll never see anything not intended for you.  Your message suggests 
that there is no HCI call to do this, which puts me out of luck.

Have you seen or heard of anyone using two BT devices in a Linux box to 
achieve a "man-in-the-middle" type of monitoring system?
