I have been deeply involved with Cable Card (happen to design Cable Card test system and leading a Cable Card project). I am now leading some DVB-CI+ project for making USB based Conditional Access Module (CAM is the generic name for CableCard like devices). The major issue in the US are operators which loooove so much milking their customer that they will NEVER EVER allow a system that will prevent them to do so. So if there is an initiative to make software based CAM make sure this thing will be carefully driven to end up in the wall. This has been done before with DCAS and will be done again. This is why the average cable bill is around 100$ in US while we pay half of that for premium package in Europe. European commission may be a bunch a picky buggers, they don't hesitate to slam the fingers of the ones who are abusing their dominant position.
