Seems promising, but I doubt it'll have the full effect by the time it actually gets passed, would probably just be some watered-down "you can emulate your own private server and we won't sue you" kind of approach but still not have any access to source or server code. Which will basically mean, you're in not much of a better spot than what PC is in now in terms of trying to make stuff work without the actual server access.
Or. you get the full game and server software necessary to run it but it will be under absolute lock and key, no-one will be able to make any kind of changes to it, which I guess I could live with, but would be equally frustrating.
Progress is progress I guess though.
