external link in breadcrums?

What we have to do for having a link in breadcrumbs whose target is _blank? I

dont want that users leave my own site.

I think it’s not possible per current implementation as the breadcrumbs does not pass the htmlOptions for the links…

BUT

The breadcrumbs are used to displays a list of links indicating the position of the current page in the whole website. So in the breadcrumbs would be only links to parts of your site… They are used to display where the user is located inside the site… not for external URLs…
