That can generally only be obtained by code running on the actual
computer. IIRC it's sent along in every IP package, but lost when the
package goes through the first router or firewall.

Lost at first router, yes. So it's available to all computers on the same
subnet. You can use the arp command-line tool to get IP-MAC pairings... if
your entry isn't in the table ping or connect to it first. (if you're
authenticating an incoming connection, for example, the inbound request will
add an entry in the table) Just be careful because ARP spoofing can only be
detected and stopped by a managed switch.
