Have this seen any widespread use? I mean, there needs to be tens of percent of users having these before they'll get used by the GeoIP people.

 People who are evil (or people seeking privacy) will intentionally put bad
 data, thus ruining the whole thing.

 I don't think self-reporting is the answer.

 You MIGHT be able to determine location based on a traceroute, though
 anycast would surely derail such attempts.  I suspect most people rely on
 3rd party GeoIP databases, and that those companies aren't interested in
 hearing from you about your location change, mostly because they are
 worried that if they do, the evildoers will overrun them with bad
 requests, or bait and switch, making their data less accurate than it is
 now without your block being correct.

 Which I can understand.
