If you have never seen it, have a look at searchme.com - search for "news". It's dog slow because this site actually loads all the pages realtime and displays them as images you can click on. The interface is, well, whatever - but it is a massive bandwidth hog.

That actually pulls the pages off carol's site realtime to make up the search pages. The user never even has to go there to be using up bandwidth. Get a popular search term, and you could end up wasting a ton of money of connectivity to keep these people happy - not to mention server resources.
You can spot them as 208.111.154.16 and 208.111.154.15
