Possible method:

1. Download KMZ from http://www.gadm.org/country
2. Upload the KMZ to application static files
3. API call to load data from the KMZ file
   • unzip the file
   • parse the XML
   • find the placemark desired
   • get the polygon geometry
   • add the polygon(s) to the map

Might have a performance penalty. Alternatively, provide instructions/method to upload the KMZ file, parse and load it into a database table which can then be queried by the plugin.
