AirTV integrating sling and OTA (over-the-air)

AirTV Streams OTA Channels to Your Entire Home and Beyond - AVSForum.com
wondering if anyone has this yet, or if it's even out. I like the idea of one device as a source, since I'd rather not bother my wife changing between antenna and box if I kill DIRECTV. But it's unclear to me how to connect to the TV-via Ethernet input on the TV and an app it seems??
Then again, would it be simpler to just change to DIRECTV NOW? I heard that is getting better.

 

It looks interesting. I'll be watching this thread.

 

I've invested in connected OTA boxes for cheap which is fine but I would have liked a streaming option. Hope this works as well as advertised.
