I was chatting with Christoph today and mentioned this. Then, because I get obsessive about stuff like this, I figured out how to do it this evening--using Javascript, XSLT, and XQuery.
The current implementation only works with Firefox. An IE implementation would be similar (though it seems like IE does not support XQuery via document.evaluate, so I'd have to walk the doc tree and do an ID match).
Anyways, if any of you are interested (because I had to glean much of this from many, many, many different websites), you can see the end result here:

Warning: My Javascript is yucky.
Update: Should work with IE now.
