Wow, I had no idea that my system fonts were trackable with Flash. That's like an instant fingerprint, as many developers and designers have at least a few custom fonts installed -- if not a few dozen.

You'd need a pretty long list of fonts to check, though. Flash makes it easier since you can simply enumerate all the fonts.
