Feature request:
Allow to generate multiple breadcrumbs to the page

Implementation:
Following the example of drupal_*_message(), rework the
drupal_*_breadrumb() functions to allow multiple breadcrumbs (nest
the current breadcrumb[] array into the breadcrumbs[] array)

Notes:
themes should be changed to support this feature

Example:
a screenshot featuring 2 example usages for multiple breadcrumbs: from Google Groups and e-commerce site

This was discussed earlier when the current breadcrumb scheme was being architected (Drupal 4.2?). Keith Instone has a few articles on the subject that were referenced at the time:
http://user-experience.org/uefiles/breadcrumbs/

I personally like our current "location" breadcrumb scheme, but if we are to go with multiple breadcrumbs we should have a full-fledged "attribute" scheme rather than some hybrid. The menu system itself should be reworked in this case to allow items to be in multiple places in the menu structure.

I, for one, am not a fan of multiple breadcrumbs. I think thats confusing to the user. If we must have multiple, there should be 'primary' which is authoritiative. Themes could them choose to only show primary.

With respect to those screenshots, they display 'related categories' which are equivalent to taxonomy terms in drupal. Thats a different dimension from breadcrumb.

I think there's not currently enough demand to change the menu fundamentally to allow multiple simultaneous "user locations." Further discussion at http://drupal.org/node/view/7331.
