Sorry to butt in on your discussion here, but I think its a little
misleading.
This innovation is not about using anything as nefarious as a s0ftc4m
 (sorry for mentioning the forbidden things ;)
It's a perfectly valid use of a genuine CAM module, which are full endorsed
(even encouraged!) in many countries.

Storing an encrypted stream is not a DMCA violation (as it hasn't been
decrypted), and I don't see using a CAM to decrypt as a DMCA violation
either (Its fully supported in myth anyway) as the CAM contains a licensed
card.
Now, I'm totally not a lawyer, nor even a developer, so apologies for
speaking out.
So the difference is merely storing an encrypted stream and decrypting it
(with a valid license) later
I don't think this is a DMCA violation at all, but I could be entirley
wrong.
Who cares wether it's decrypted sooner or later, the copyright holders might
be more upset it's being stored at all, but they'd be more upset if it was
stored unencrypted (as currently) surely?
