This had me so curious, I did some digging and found that packets do not contain a MAC Address. This point is also stated quite clearly on a number of the packet sniffer software websites out there.

Examples of what is contained in a packet can be found at http://www.netfor2.com/tcp.htm and http://www.securityfocus.com/infocus/1845 and at http://www.erg.abdn.ac.uk/users/gorr...t-decode3.html Those are just a few examples of what I found, there are many more.

So, I am sorry moetheman, but you appear quite wrong in this. I have yet to find anywhere that says that a MAC Address is discoverable outside a LAN without broadcasting it or using it as part of a secure login schema.
