Just a footnote-like comment:

I was also playing with ifwatchd the other day, but found it somewhat 
troublesome
for wireless networking. As I want the ethernet to go down when the wpi goes up,
automatically associates and gets an address from dhclient, the events get mixed
up.

(Furthermore, I want this scenario to happen when I hit the radio kill -switch
that my laptop has. To accomplish this, I wrote a tiny, naive daemon[1].)
