OK, I'm convinced that direct DOM access is a bad idea. seamless was the
use-case I most cared about anyways. In theory, if we use seamless + CORS
for the @src load and any navigations of the frame (including via
Location), then this should be feasible, yes?

Alternately, we could add a special http header and/or meta tag for this,
like x-frame-options, but for the child frame to define it's relationship
to the parent frame.
