Hi,
I think you can use IModel<String> for the dropdown. This will be the
country code.
The transformation from id to name and back (if needed) can be moved to a
custom IChoiceRenderer. There you have access to the current locale for
each rendering.
CountryChoiceRenderer can delegate the actual work to
CountryDatabase/CountryProvider/...
