I have gamecenter for the PS3 and the kool thing is that you can subscribe to the NHL Vault for $5 a month and still see all the games (minus the random blackout games) live on the PS3, but not on PC if that matters. I mean I don't know if they fixed it for this season so it might not be true still. The HD stream is hit or miss depending on your connection really. If its bad it'll drop it down a couple of notches like Netflix does, but when its running smooth it looks amazing.
