Bluetooth MAC Address

I am evaluating to regularly run blueproximity and libpam_usb to get and restric access to my computers, but, since they just check for the configured bluetooth device (in this case a mobile phone is the usual choice), the problem is related to the uniqueness of the MAC address.

Googling a bit I did not find any definitive info.
Thus, the question: is there any bluetooth device that can dynamically change its MAC?

If it were, these solutions should be considered completely useless with no handshake implementations, or - at least - just proofs of concept.

Thanks in advance, bros.

Re: Bluetooth MAC Address

Depending on what level of security you need, the simple answer is 'yes' ...simply because it is technically possible. Somebody could also pickpocket your cellphone.

I need a sorted list of all random numbers, so that I can retrieve a suitable one later with a binary search instead of having to iterate through the generation process every time.
