Killer list, Doc. Here's the comment I just posted:
Along the lines of Sylvain's suggestion about financial data consolidation, you didn't mention health data (other than QS data). The value of having a single consolidated view of my health data and control over sharing it with the health care professionals of my choice would be enormous.
Another category is insurance. I would love to have all my insurance coverages related to me, my family, and my possessions available in one place I can view, modify/update, and share them. It would not only eliminate a whole file drawer, but enable me to manage them much more easily in true VRM fashion.
