The security problems are very different actually. The tab sharing capabilities are limited by the same-origin security model. If a page includes an image from another domain, all the other end can do is include the same image. The same goes for iframes. Images are probably OK, because they usually show the same things without the site having to get access to content. With an iframe, there's a good chance that each end is going to see something different, or that content can diverge without the tab-sharing application's awareness. But it does go to the point that webrtc isn't necessary for this sort of use case. In fact, sending video is pretty wasteful.
