Host bound Serial Numbers
This module provides a host based serial number. The serial numbers are generated from hardware serial numbers. E.g. mac addresses or harddisk serial numbers. No assumptions can be made about the serial numbers, although they may currently look suspiciously like mac adresses ;-).
Host Serial Numbers stay the same while the hardware stays the same.
There can be several host serial numbers at the same time, which can
be retrieved through (host-possible-serial-numbers.

be found in the possible serial numbers.
(valid-serial-number-for-this-host? N) : boolean
Returns #t, if the given number N is part of the possible serial numbers for this host; #f otherwise.
