Yup. The diagrams on the web page all show a set-top box being used to
decrypt 
the cable. It was beginning to look quite desirable till I saw that...

Yeah, from the diagram I would guess we would need a STB, this device, plus
a DVB tuner.
Change the channel on the STB which would then change the channel going into
the device and feeding into the tuner, no need to change tuner channels ala
VCR's in between a STB and a TV.
PROs: Tf the device can do what it says it can, ability to decode any
channel.
CONs: You need a STB the device, and a DVB tuner. (3 pieces of hardware)

What they need to do is broadcast QAM in the clear or make a QAM tuner that
can accept the cable card.
