Note this approach works 99% of the time, but can go wrong (or at least 
be very confusing) if the user has installed any devices which have an 
in-built MAC address (e.g. a USB Wifi card, perhaps to get better reach 
than the in-built wifi gets, he says from experience :-).  This may be 
the MAC address reported first, giving an "ID" which can later change.

It might be better to do a filter on ""Physical address" and then regard 
each of the physical addresses as valid IDs (disregarding the 
00-00-00-00-00-00 ones for virtual adapters).

And as Peter said, a smart user can find a way around it anyway, a smart 
and malicious user will definitely get around it.
