eKstreme has done some excellent work with his latest tool, recognizing a hot topic and underserved market, then delivering. The domain geolocator tool looks at the TLD extension, the hosting country (using an IP geolocation database) and the locations of inbound links for an impressive overview of the factors that might affect your domain's rank in certain locales.

Domain Geolocator Tool

I tried a few domains and the most interesting piece to me was looking at the hosting locations of the many sites that link to those domains (you can see these by clicking "details" from the initial results screen). Data like this on a potential client or competitor's site is probably of much greater value than checking your own properties.
