Google is hardly the poster child for empowering users to free themselves from the control of internet firms, but a new tool called M-Lab (Measurement Lab), announced today in association with the New America Foundation's Open Technology Institute and the PlanetLab Consortium, will detect if ISPs are engaging in throttling or blocking particular applications. You pay for an internet connection like any other service, right? What you see is what you get? Not exactly. Internet service providers (ISPs) have been known to throttle, or limit, the amount of data transmitted from certain applications, most often peer-to-peer (P2P) file-sharing sites and BitTorrent services.
