As far as I am aware MAC addresses are only, or at least predominantly, used in the ARP protocol, which is used in LAN situation. ARP packets will not be routed over the internet. Therefore I would say that finding the MAC address of a remote host over the internet would be very difficult.
That is true (when using ARP or the MAC address on received frames). There are sometimes other ways to get remote MAC addresses (The Windows ports often give them aways easily, so does SNMP, and some IPv6 addresses include or are derived from the MAC address). I would like to print the MAC address for a host based on the packets received. As Testic mentions this will only work on a LAN. And of course only on Ethernet and similar systems (like 802.11B). It is still valuable enough that I hope to add it this year. If someone wants it desperately enough, you can consider sending a patch earlier :). I might also do a number-of-hops test of some sort both as useful information in itself and to determine whether the next hop is the actual target and thus corresponds to the received MAC.
