You do understand, I presume, that your MAC address never travels off 
your LAN anyway? When packets are routed to other networks they will be 
encapsulated by other devices, so while the IP (network-layer) 
addressing remains the same over all hops, the originating device's MAC 
address is removed the first time the packet is routed.
