Verily you are correct, as I found today. While the Rack has torched a 
power supply, pogo has now taken its place. It is carefully configured 
for symmetric key, but refuses to send an authenticated packet. Solaris 
pogo and FreeBSD hepzibah commit the same crime. In addition, the 
broadcast shows up at the client with destination address all zeros.
