It’d be awesome if you could even self-host streaming computers/servers and Valve didn’t host all of these, but instead certified data centers (like the “official” Steam Machines) or something like that.

You could guarantee a good service with a certified data center but you could also choose to self-host or go to a non-certified game streaming service. De-couple the software from the service, so to speak. It already worked well in gaming for self-hosting community game servers for tournaments, custom modes, private WAN parties and so on.

Sure, it’d still be proprietary, but OTOH way better than any of the alternatives. Maybe FOSS implementations could follow.
