Aren't they already confused enough when any time I use my EVDO or 3G
Tether that someone believes I've been magically transported to New
Jersey or wherever the handoff is? ;)
Understand the logic behind it, but you probably statistically have
just as much chance of being correct as you do incorrect.

a radius of around 200 kilometres.
Finally, they repeat the landmark search at this more fine-grained
level: comparing delay times once more, they establish which
landmark server is closest to the target. The result can never be
entirely accurate, but it's much better than trying to determine a
location by converting the initial delay into a distance or the next
best IP-based method. On average their method gets to within 690
metres of the target and can be as close as 100 metres - good enough
to identify the target computer's location to within a few streets."
It seems to me to be a rather flaky way of finding out your
estimated location. But I guess it could be helpful when the
objective is just to create some global database of demographics for
marketing and privacy invasion purposes, where specifics of an
individual's exact location don't really matter.
Besides the latter can always be subpoenaed. ;-)
One more reason to use VPN and other such techniques to hide your
