for that map, i cleaned out a bunch of the obviously bad points (manually &
with some simple sql rules), what was left was stuff i couldn't really make
a judgement call on--ie it *could* be valid lat/long.

well if you can somehow get their country (say maybe nigel's
inetaddressLocator) at the same time, you could simply intersect that point
with their country & return whether that point is where its supposed to be.
i suppose it would be simplest to show folks where they just they were.

>(http://www.idlewords.com/weblog.09.2003.html#272); if anyone has
visual feedback seems the cheapest way to get cleaner data into geoUrl. but
i'd also say that determining if a given point is within a single country
shouldn't be that resource intensive.
