I like idea to protect the network funcionality against people like this "downloader".
If you don't have the time/effort to exert on one method, another is to kick down the neighbor's door, open his BitTorrent client (you may have to get him a better one such as BitComet), and set an upload/download limit. There's another important thing. You have to limit the upload or you're screwed for the download too. That may WELL be the problem. Limit the upload to, say, 32k.
