indeed. or at least, this isn't the first time it's been seen (and my now-expired I-D describing the best way for apps to deal with NATs mentioned something similar). but it doesn't really solve the problems associated with ambiguous addresses. it still doesn't provide a reliable way to talk to that host in the presence of ambiguous addresses. it only keeps you from mistakenly talking to the wrong host when two hosts use the same address.
