You can already purchase devices that allow access to local HD channels via Clear QAM on computers and other devices, and many current TVs have the functionality built in. The only requirement is that you pay for a basic cable subscription, else the QAM signal won't be sent to your jack (i.e. just having cable Internet is not sufficient.) I don't see how this is any different since you only mention broadcast stations. If the device lets you access cable channels on the other hand, then there might indeed be some issues regarding streaming.
