The biggest hurdle was Microsoft allowing Xbox Live to do this (without any forced Windows Vista or 10 crap) after 15 long years of its existence. Just another thing PS3 and PSN has been capable for almost 10 years and is now another awesome upcoming Xbox feature pushing the Xbone to easily surpass the pitiful 360 even more.

And Microsoft have still yet to actually release or even announce a game that is capable of this or if the power is in devs hands right now, as the dev said above “we just need to be able to have the go ahead”. So there is a “go ahead” requirement too even when you have it all in place and ready to go???
