@scottjehl @filamentgroup Very clever, yet not universal due to the Same Origin Policy: "If document's origin and the origin specified by the current settings object are not same origin-domain, then return null [instead of the iframe's contentDocument]"—html.spec.whatwg.org/multipage/browsers.html#concept-bcc-content-document. Maybe worth pointing out.
