Are there projects like this that let me embed a third-party URL instead of direct code? So if a publisher provides me with a link to widget.js, I could just run some sort of Adsafe.executeInWrapper(http://example.com/widget.js http://example.com/widget.js) Most providers in my experience don't want you to embed their actual JS code, because then they lose the ability to do updates and fix bugs without contacting every single customer to upgrade.
