Menu for Personal and Business version of site

I want a 'Person / privat' and a 'Bedrift / business' part of the site.
So, when the user clicks on one of them, the submenu is / looks the same, but leads to different content.

How should I do this? (hopefully without hard coding too much).
It should work (for the user) almost like having two languages.

  1. custom viewlet above global with nav/links pointing to the two folders
  2. apply navigation root on the two folders, so the main menu is rendered there (there is a behavior).

Thanks a lot

I would probably need to have a 'default page'.
Would it be OK to set 'folder1' as 'default page' of root ?

Or a Link as redirect?

Possible, but the site might 'look slower on google' (?)'
