Glenn- Legit concern or not, the cable operators are very sensitive to the possibility of having their content hijacked. But the point is that MoCA is something the operators *are* comfortable with, which is why it’s a preferred method for in-home networking among them.

I don’t understand why there is an issue with keeping the video secure. When the MPEG-2 transport stream comes in over the cable it can be scrambled. I assume all the premium channels like HBO, SHOW, MAX do such scrambling on all their channels. You then need a cablecard or the equivalent functionality, as well as key exchange protocols with the head end to descramble the content. I assume that if the transport stream is sent over MoCA or stored on a DVR’s hard drive or sent out over FireWire, it is that same scrambled version, and if you don’t have a way to descramble it, you’re out of luck. Is this not correct?
