Custom localization based on user selected locale

• Localize all your portal settings properties (Portal name, keywords, skin, container, copyright text, etc)
• Localize all you tab settings (Skin, Tab name, description, keywords, etc)
• Localize all your module settings (Title, header, footer, container ,etc)
• Enables search for localized data
• Can use a cookie, querystring parameter or browser specified language
• Can use GeoIP database to detect locale based on the client IP address
• You can set the detection order
• You can enable/disable a detection feature
• An automatic replacement can be done to change all links in page to include the language parameter
• SOLPART menu links will be automatically replaced to include the language parameter
• You can create your own custom replacements based on current locale and regular expressions
• Create regex based replacements for each locale

This allows you to change the language of each menu item. I haven't tried this before but I would think you can "delete" for particular menu items. 

Or it looks like you can change the skin based on language. So you can swtich the menu too.

I love this module.  With this navigation module, you can add/delete particular items.

When you figure this out, post it here. I am interested in the result.

Good luck!
