fyi (assuming this guy knows what he's talking about :-)):
http://mhonarc.axis.se/bluetooth-dev/msg00487.html :
Each Bluetooth device has a globally unique device address, much like a
MAC address.  This is how you address Bluetooth devices.  There is also a
user-friendly name for each device.  You could think of these as being
analagous to an IP address and a host/domain name, although they're not
equivalent.
