asp.net localized sitemap, bread crumb and menu

Here is what I want:

Site has 4 languages (Ch, Fr, It and En), everything is localized. I have CSS Friendly control adapters in place, so that I can use Superfish JQuery menu for navigation (other suggestions?). I want to somehow tie this menu, and the bread crumb to the localized sitemap.

My concerns:

1. Is it doable? Can you give me some suggestions / best practices?
2. How about SE开发者_StackOverflowO with sitemap localizations? I would like to have titles localized, so that menu and the bread crumb show proper names on different languages. I'm little concerned about SEO with all of this.

Works like a charm ... :)

I wont use ASP.NET sitemap for SEO, but instead I will generate a google-friendlier XML sitemap.
