I don't think that's quite right.

Yes, it's true that the Verizon cable modem/router does suck the guide
data off and spit it back out via coax to all the Verizon STB's, but
that's guide data, not channel data.  The HDHR Prime or other cable
card devices have no access to the guide data at all, only the channel
map, which is something completely different.
