The most impressive plug-in I'm told about allows for streaming from an Xbox console to a Mac running Galaxy.
Just click on the Xbox game in your Galaxy library, imported through the connection to your Xbox account, and it'll boot the game up on your console before, somehow, sending it to your Mac.
I doubt it's as elegant as it sounds, but it's possible because someone wanted it to be possible and made it happen.
That's the real hook here.
