Okay, good.

It would only be BT <-> EoUSB. For WLAN, I think we should just use the address in the "ROM" of the WLAN module. > I have very little knowledge of the bluetooth security world. Me neither :-( Also, I don't know if there might be any protocols in BT that would expect to have their own MAC address, similar to EoUSB. I hope not. I think we may want to make the address blocks as small as 16 bits, to keep their management flexible, which really means about 20'000 assignments or 14.3 bits of randomness, given that we use groups of three. So they wouldn't be too hard to search, but they'd at least limit the accuracy with which one can predict MAC address or production date, given the other. Thanks, - Werner
