Indeed, and unlike TCP spoofing and man-in-the-middle exploits, to spoof 
a MAC address you don't have to coordinate with long-range checksums or 
ongoing sequence windowing or serial numbers, so there's very little to 
MAC spoofing other than getting the desired 48 bits of MAC address into 
the packets.

It's my impression that most link adaptors have a promiscuous mode and 
programmable (overridable) MAC addresses, so MAC spoofing is 
essentially trivial nowadays.
