Rewrite URL for multiples website/store views

Question

I'm using Magento 1.8.0 with multiples websites for each country, for example

1. USA (Website) with english (store views)
2. France (website) with french and english (store views)
3. Switzerland (website) with french, german and english (store views)

Actually, when someone visit my website, I use a geoIP script to redirect it to the right store views.

$geoPlugin_array = unserialize( file_get_contents('http://www.geoplugin.net/php.gp?ip=184.172.117.120') );

//Get country code
$code = $geoPlugin_array['geoplugin_countryCode'];

//Get browser Language
$browserLanguage = $_SERVER['HTTP_ACCEPT_LANGUAGE'];
$browserLanguage = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);

if ($code == "CH") {
    switch ($browserLanguage){
        case "fr":
           $mageRunCode = "ch_fr";        
            break;

        case "de":
           $mageRunCode = "ch_de";        
            break;  

        default:
            $mageRunCode = "ch_en";       
            break;
        }
}

I choose to add the store views to the URL, because my store are SEO friendly (I think). ch_fr, ch_de, ch_en, us_en...

So my website will look like : www.mystore.com/ch_fr/

This work fine it the user goes to the homepage, but If I want to share a link to a specifc produc on Facebook for example, I can't. For example :

I have a product, www.mystore.com/us_en/category-in-english/myProduct.html But in Swiss-french, it should be : www.mystore.com/ch_fr/categorie-en-francais/monProduit.html

Ideally, I would like to share a link like : www.mystore.com/myProduct.html and to be redirect by the same geoIp to the right country/language.

I think a good approach to this would be to implement a router which servers before 404 error.

The router checks, where the customer is from and where to redirect. If this is possible you have a controller which does this.

If not you just skip the router and serve a 404 error.
