'While sources familiar with the new initiative emphasized that it is being seen as a complement to CAS [a.k.a. six strikes] and not a replacement, the very emergence of an alternative raises questions as to the viability of CAS, which has been criticized for myriad reasons ranging from the questionable strategic rationale of punishing subscribers to an implementation that has been characterized as scattershot. How the two systems would coexist is unclear.'" Comcast will be inviting other ISPs to join its new system as well.
