A proof-of-concept, even if it doesn't involve any NM code at all, would
be greatly neat.  Bonus points for doing it using glib, since that's
what NM uses and we'd have to convert the proof over to it anyway.

The configuration information, ie what MAC address to arping and what
corresponding static IP to assign to the card would be derived from the
distribution's specific configuration files though NM's configuration
abstraction stuff.

I'm assuming that when we notice a link switch in NM, that we can fire
off the arping requests and then, with a short delay, start a DHCP
transaction.  If we receive a reply from the arping, we cancel DHCP and
set the static IP on the device.  If no reply from arping, we wait until
DHCP has finished with success, or timed out, and continue with the
existing behavior.
