> You would need an HDCP license...

The suggestion is for an illegal device, no need for licenses in that case ;)

The easiest way would be to extract the pint glass graphic over the wire (sitting in middle of the HDMI cable the set top box to the TV) then transmitting that to other establishments and overlaying that graphic in between the set top box and the TV (the best bit is that you wouldn't even need to decrypt the video, just overlay the graphic).
