Well, that’s pretty amazing. At intelius.com you can do a full background check on anyone in the US, online, instant, for only $39.95. With it you get details about home ownership (all real estate actually), history of marriage and divorce, and criminal records (yummy).
I always knew this would be technically possible, just practically pretty difficult to accomplish.
Someday, I believe, it will be offered world wide, and it will include the full DNA string, picture, and videos of important moments in that person’s life.
