At the end of the instance referencing discussion, Van Lindbergh
brought up the idea. We discussed it with several people both in the conference
room and over lunch. I believe that the main objections were that not everyone
would have an IPv6 creation scheme, whereas UUID generators are ubiquitous. The
other was a vague concern about "revealing internal structure", but since the
information "revealed" would be the exact same info in the instance's public
network info, it didn't strike me as a serious concern.
