Congress asked to investigate Internet “supercookies”
- I just don't see any good that can come from legislators getting involved here. Also, if you want to do your own supercookies, check out: http://samy.pl/evercookie/ 
- I investigated supercookies (evercookie? no mention of samy in the article?) the other day in all of 5 minutes. - Yes, they work on most modern browsers, and are very difficult to remove entirely. - No, they do not store anything on any modern browser surfing in "privacy" mode. - I was pretty disappointed to be honest. I was hoping to use them to track fraudulent free trial abusers. 
- Did you know that Java has its own version of Flash's Local Shared Objects? They are also known as "muffins" and have pretty much the same abilities (including resurrecting HTTP cookies.) So far they aren't used much, but any new regulations that apply to one are also likely to apply to the other. 
- This is not the answer. Why don't we invent technology that beats the "supercookie" instead of passing laws that restrict innovation and ideas? 
- Congress only wants to investigate because they're hoping to get new sources of data to use against the people. 
- Hey, what this .swf file? Oh, that's a "Small Web File". LOL! - Flash just needs to die. It adds nothing to my "user experience". Except stealth tracking of course.
