I'm interested in a solution to this as well.  The context for me is that 
I'm attempting to build a component that would be used by a few dozen 
different applications to apply a common theme to all of them.

  <body>
    <our-common-theme>
      <div>All the content</div>
    </our-common-theme>
  </body>

The one big catch is that the <our-common-theme> component must inject some 
meta tags the parent DOM's head.  We've had a hard time getting that 
working with Polymer.
