But I think that if the author can extend the plugin with the Geo IP functionality it will be just perfect!
For example: there is a free GPL Joomla component which installs all the GEO IP data in to the local DB of the site, ad after that the plugin can FAST check the IP and fill the right customer Country in to the checkout process ...
Here is the link to the the Geo IP component:
