Multi-country PLUS multilingual site – an idea..

Hey guys, I would love to hear your comments on my concept:

The site is supposed to be basically accessible from anywhere, but for the countries Germany, France, Switzerland, Netherlands and Belgium, there will be certain country-specific content that should only be shown when the user is located in one of these countries.

In addition to that, a language selector will be there with : de, eng, fr, nl.
So 4 languages.

My first plan was to build a multisite with subdomains and use WPML as translation tool. But that would mean, that certain contents, that are accessible to all countries have to be stored 4 times PLUS in 4 languages… that sounded very redundant to me.

Now my plan is the following and I would really like to get some comments:

No Multisite, just a normal WP installation. Create any content just once plus translations.

Give every post/page a custom field, like a “country” custom field.
So every post/page could have a field “Germany” or “Germany”+”Switzerland” or “Netherlands”+”Belgium” and so on.

Then geotarget the user or just ask for the country by a drop-down- list.
Get the country code.

Add conditions to the template loops:

If user is from Germany, just show posts with custom field = Germany
If user is from Switzerland, just show posts with custom field = Switzerland

and so on.

In addition WPML lets you pick the languages, so an english speaking user from Switzerland gets only the posts from Switzerland but in english.

Does that sound logical or have I made a big mistake?

Thanks for your comments!
