Well, this looks like the next hack/scam feature. I really hate to think of the sort of rubbish that this will cause. > Google says portals allow users to navigate inside the > content they are embedding --something that iframes do not > allow for security reasons. Surely this is exactly why the "portal" shouldn't do this either? Why not work towards fixing the security issues of the iframe? Regarding pre-loading content in links, they could just implement this in the browser if they think it's really that important. This will destroy your mobile data. I really wish they had sat down and discussed this with other browser teams to flesh it out. I think part of this is in getting the jump on other browsers, this really will take a long time to implement securely.
