That's probably a FAI-complete problem. See also: http://xkcd.com/810/
Would people use it?
A thing I would like is this. I would totally enable this on LW if it was an option. (And if someone volunteered to write a Firefox plugin to achieve the same client-side, they'd have all my gratefulness.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
