	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.
