I've read that CPRM can be applied to digital BROADCAST cable/DSS signals. This does not sound like a 'good' thing.

1) Is this true?

2) Is this being done now at all?

3) Will this be done anytime soon?

4) IF this is a valid future concern, can it in any way influence a current/near future purchasing decision? (Hardware that may or may not circumvent, or allow 'flexability' in dealing with this issue).
