CRISTAROL writes "Comcast has been sued by a California resident for blocking BitTorrent and other traffic. 'John Hart describes himself as a Comcast customer who has seen performance hits when using "Blocked Applications" targeted by Comcast's traffic management application, Sandvine. In his complaint, Hart says that Comcast severely limits "the speed of certain internet applications such as peer-to-peer file sharing and lotus notes [sic]." Comcast accomplishes this by "transmitting unauthorized hidden messages" to the PCs of those using the applications.' The lawsuit comes on the heels of an FCC complaint over the same issue."
