FiOS already does this, in a way.

I recently switched to Verizon FiOS for TV, which necessitated the installation of a FiOS branded Actiontec router, so that the cable boxes can access the Internet over MoCA. The router has QoS rules to prioritize VOD traffic over all other traffic (which is why I purchased an Ethernet to MoCA bridge, so I can use my own router).

AT&T U-Verse also works in a similar way. One pipe carries data and video services. The circuit is provisioned to accommodate video services. AT&T could technically offer faster packages to customers who did not use U-Verse video service. It's very difficult to micro-manage how providers want to utilize their network bandwidth especially when we're looking at services that do not transverse the public Internet.

There is actually a similar FiOS xbox app as well. I am not familiar enough to say if it gets preferential treatment on the network, but you can stream a subset of live TV channels and use it as an alternative to the cable box, although I don't think it has had enough polish to inspire a full time switch.
