Detect & display Country in notification to administrator?

I know you can add additional info to the notification emails, like the user's IP address, user agent, etc.

I'm wondering if there's a way to detect where in the world (country) the user is and display that? I don't want to add a Country field to form. I want to find out their country "behind the scenes".

I know it's possible to geolocate an IP address using sites like this: http://www.ipligence.com/geolocation ...Is it somehow possible to build this geolocation into Gravity Forms?

Probably requires a customization, but just figured I'd ask.

Thanks!
