Is there any way to get some UNIQUE, unchanging value from the user’s computer, such as MAC address etc, via ActionScript? IP Addresses change too often, and even though MAC addresses are fakeable, at least it is a bit of protection.

I can find many uses for this, including making it more difficult for people to copy over SharedObject data from computer to computer.
