Not sure how it will play out in Congress. I suspect it'll come down to how much Comcast and Time Warner feel threatened. Nobody gives a shit about Joe Consumer or music streaming services. But TWC starts squawking about it and Congress will back down very quickly. Cell providers will also scream pretty loudly about it.
It's actually a fascinating conflict of interest brewing. TW creates a great deal of content, so they have a keen interest in deterring piracy. Yet they're also a major broadband provider, so they damn sure don't want to face liability for what happens with their tubes. I suspect the vagueness of it will frighten them enough.
I do know that Obama staffed his entire DoJ with entertainment industry lawyers, so this is really something I thought more likely from him than from Congress. I actually saw this happening years ago, just coming from a different direction. Needless to say, he certainly won't be vetoing it if it passes.
I'd say that the real test with be with the Supreme Court, and in this climate I don't see them intervening. That something has the potential for great abuse doesn't concern them in the slightest. If The Man says that he'll play nice with it, that's good enough for five of them.
