At least for me, the "menu structure", as far as breadcrumbs are 
concerned, is not the way Drupal defines a menu (e.g. a 2 miles long 
array of paths and callbacks), but the way the user perceives it - a 
simple, visible hierarchy, that is defined by the administrator, through 
the admin/build/menu interface.

So node/123 could show, by default, its menu parent, if there is one 
defined, or "main", or "home", in case there is no parent (in case 
node/123 is not included in a user-defined menu).
