Whoa, this is by far the most interesting news here. It occurred to me that an evil government could hijack all HTTP requests, slip a script into the <head> and literally monitor every keystroke and click and mousemove for their web users, using their browser as the key logger and with little knowledge by the end user (unless they scan the source of every script). That's freakishly powerful spying capability, beyond just tracking and logging requests/IPs/contents.
