That's the best option for now, but of course there are security issues
with that since any MAC address can be spoofed.  There are vague plans
to attempt to automatically identify wired networks by listening to the
wire for a few seconds and detecting 802.1x EAP-Request Identity packet
s or ARPing a specific IP address and matching the returned MAC.  This
feature would  have to be opt-in because obviously it would delay
network connections.

If that's something you'd be willing to work on, that would be great...
what do you say? :)


What about using IPv6 RA messages to do that?
