Country Filter plugin allows you to control the visibility of WordPress elements depending on the users country of origin. You can hide or show certain elements of a page or some sections of a post from users browsing from a particular country.
For example you could have a ‘donate’ button on a sidebar that displays only if the user is browsing from France. Or you could hide a particular paragraph in a post for users from a particular country. This can be used by marketing people to deliver targeted content to audiences.
Developers and designers could use the plugin to load different stylesheets based on the users country. Services like hulu.com uses techniques such as this to constrain viewership to a particular country.
