Ordinarily, there's a hard cross-orgin security policy separating URLs like: file:///Users/user/plain.txt From: http://example.com/plain.txt I feel like something that blurs this boundary could be dangerous for non-developers and less techincal folks. Things like Flash and Java applets often bridged that gap, causing many problems. I wonder how many people understand the reasons for a clear distinction between browsing files on your machine with an FS explorer, versus an isolated file store jailed or sandboxed to the browser?
