 However, I can front a non-appspot.com domain with another non-appspot.com
 domain. For instance, I can front youtube.com with google.com.

 {{{
 neel at xb2:~ % wget -q -O - --content-on-error -S https://www.google.com/
 --header 'Host: www.youtube.com'
 }}}

 And it fetches YouTube's homepage.

 But this probably won't work for us because we have to use appspot in
 order to be able to front.
