 I'm going to guess that ifconfig -w 15 -W 5 did infact wait the time.
 I'll also guess that my recentish changes have unmasked the actual
 problem in that for some reason DaD isn't completing on your interface.
 
 Could you wait a few minutes and then look at the ifconfig output again?
 Guessing the addresses still say TENTATIVE.
