Give a small taxonomy going into categories and labels that I think are useful when talking about identity;
Walk you through what a layered conceptual model for identity could be like;
Talk about the privacy implications for how we go about implementing things;
Hopefully convince you that the closer to the edge we process things, the better it is for the user, but that the edge does not guarantee privacy (no matter what the Blue Behemoth whose name starts with an F would like people to believe).
