EFF launches tool to monitor ISPs for bad behavior
It's also a command-line tool, and still in alpha, so it's not necessarily for everyone. If you're comfortable with this kind of app, and you're concerned about your ISP's behavior, definitely give it a go. How exactly does it know whether your ISP is fiddling around with your bandwidth? The EFF says, "It will spot IP packets which are forged or modified between clients, inform you, and give you copies of the modified packets." It recognizes packets injected or modified by some of the most popular tools ISPs have been using to mess with p2p traffic, including SandVine and AudibleMagic.
