   And MAC addresses on your LAN interfaces _should_ be unique, except for those   
   vendors who cheap out and don't invest in a properly managed source of MAC   
   addresses to assign to their adaptors.   
      
   And crypto-hard random numbers _should_ be good enough; get 128 bytes and the   
   collision odds are small even to the heat death of the universe.  But you   
   only find out your numbers weren't "random enough" when it's far too late.
