Sounds good. If you would like to start doing some work in this area,  
please let us know about your specific ideas.

Maybe for your (2) above we could make tests where certain parts of  
the page wouldn't dump. That way the test could be self documenting  
but the part that dumps wouldn't be affected by the text.
