I followed the thread and found a link to a Pipex statement which effectively says that their fair use policy allows them to tinker with what we download (however, at off peak times - midnight to 6am, we are welcome to do what we want). http://www.pipex.net/legal/changes-faq.php

As my web browser downloads still downloads at a fast speed, I wonder how Pipex is able to selectively cap Limewire? Does it affect all gnutella applications? Does it affect other networks?
