Don't hold your breath on this. Way too many obstacles to fight in the non O&O markets.It would really be the icing on the cake if they could add a national feed of all the major networks. I would vote for the DC locals.
Looks like they closed the WatchESPN loophole. I tried to watch a WatchESPN stream from my computer while my daughter was watching Disney on the Roku 3. As she screamed about the TV not working I relaized the WatchESPN was kicking it off. Tried from my phone and it kicked off again (but it did display a message). And then for some reason the ESPN gamecast was trying to invoke WatchESPN because even that was kicking me off. But that could have just been PC wierdness.
Hmm. I'm still able to do WatchESPN and have Sling on something else.
