It appears that "streaming" infringing content is considered to be a public performance and thus exempt from felony prosecution while "reproducing" or "distributing" infringing content does. I honestly fail to see much of a difference between "streaming" and "distributing" so I am in favor of making the laws more consistent. Whether they should warrant felonies is a different discussion.
You could also make it consistent by making public performances felony charges. I feel an Emerson quote coming on very shortly involving hobgoblins...
Note, you do raise a good point, I'm just not sure that the consistency we want is in the direction that we're going in. Like you say, a separate discussion.
