This post is a little rambly... Basically you can get a standard DNA paternity test and then line it up with databases that are developing on the net... if everyone got a paternity test done you could track your genetic degrees of separation from anyone else. If you're one of those people who has no idea where the hell your ancestors lived you might get a good general idea through this database. (I had the good fortune of having a cousin who became obsessed with geneology in retirement and figured out exactly where my ancestors lived and all kinds of other neat information about them... ) I'm glad we're fairly well along the way toward seperating the concept of blood heredity and legal power prior to the invention of this sort of technology, but I agree with the poster that this sort of thing is going to cause some static in some of the older cultures.
