The technology is there for this kind of thing to work pretty cheaply. Projects like the Nvidia Shield and the PlayStation Vita's Remote Play capabilities on the PS3 (not to mention the recently announced PlayStation Vita TV's PS4 link) have shown that the average home broadband network can readily stream game audio and video from a computer in another room while also accepting and tras*mitting remote controller input, all without significant latency (Digital Foundry pegged the round-trip speed at a playable 100ms for the Shield in testing). As Newell said in February, the key to making in-home streaming mainstream is to make it work seamlessly without any worries about pairing devices, configuration, audio syncing, and input latency issues.
