Espacially this would be very hard if anywhere between two routers is no ethernet-link but ATM or any other Layer2 protocol. In no other Layer2 are ARPs present.
Uhm, no. ARP is not restricted to Ethernet.
As ATM hast no MAC adresses, ARP would not work. There you use ATMARP, similiar to ARP on ethernet. Ok these are also 'ARPs' but not that ARP we are reffering for spoofing.

And also written in the first PDF document I refered: http://www.rootsecure.net/content/downloads/pdf_downloads/arp_spoofing_intro.pdf
"This paper deals with the subject of ARP spoofing. ARP spoofing is a method of exploiting the interaction of IP and Ethernet protocols. It is only applicable to Ethernet networks running IP."
And as we talk about getting the MAC of a network card on the internet, which does not appear or travel through ATM except by Eth-over-ATM.
Every network technologie hast something similiar to address resolution ARP, but they are not dealing with MAC addresses as ethernet does. As you can see, I refer ARP as 'ethernet ARP' as the most common situation.
Sorry for the simple misunderstanding as I only talked about 'ethernet ARP' as we are taking about MAC addresses.
cheers Frank
