The sad thing is that this will only be used for nefarious purposes. Imagine a disaster like the tsunami here in Japan. It's conceivable the phone company could provide data updates for each user until the phone or the cell phone tower is overwhelmed with water. You could get a report of every person known to be ok and the last location of every missing person.
If this sort of usage was possible, people would understand the privacy they are giving up and appreciate the benefits.
Unfortunately, that sort of usage will never be built out. It will only be used as a when required by a court. Apple has taken a small step in this direction with the find-my-iphone feature, but I think it could be made much more accessible to the end-user. If people are going to forfeit privacy, at least let them benefit from it.
