There is an important difference between transport encryption, and
content restriction marking (copy freely, once, never).  Yes, with
Comcast, everything is encrypted (to the premise), but Comcast, in
general, marks most content (exceptions noted) as copy freely,
which means firewire can capture it from the STB.  So can an OCUR
tuner (HDHomerun, Ceton, etc.).

Clear QAM, as you state, is going away in many markets, and
Comcast, having previously rolled out all digital service (a FCC
requirement to encrypt the QAM transport stream) was able to
do so rapidly (and either is, or is mostly, finished at this point)
after the FCC allowed MSOs to do so.
