it relies on the requested path to work out how to split the breadcrumbs, it alsoo requires that every component of your path is accessable, should be a good starting block though.

  def breadcrumbs(sep = "»", include_home = true)
    levels = request.path.split('?')[0].split('/')
    levels.delete_at(0)

    links = "You are here: "
    links += content_tag('a', "home", :href => "/") if include_home

    levels.each_with_index do |level, index|
      links += " #{sep} #{content_tag('a', level.downcase.gsub(/_/, ' '), :href => '/'+levels[0..index].join('/'))}"
    end

    content_tag("div", content_tag("p", links ), :id => "breadcrumb")
  end
