* When someone else is watching the TV at home, you can go to a different room in the house, plug your gamepad into a USB port on your computer, and play the games from your computer while they run on your console across your home network. Since you are playing at home, you have plenty of bandwidth, no Internet bandwidth caps, and minimal latency.
    * If you want to play a game with one of your friends, but they can’t come over, you can grant them access to play with/against you on your console from wherever they are (provided they have access to a broadband Internet connection). They can simply download the Spawn Player and install it on their computer (free of charge), plug a gamepad into a USB port on their computer, and play in multi-player mode on your console remotely while you play in the same session on your console & TV.
    * If you are travelling – at a coffee shop, airport, hotel, etc. – you can play your games using the Spawn Player from anywhere you can get a broadband Internet connection as if you were at home. You can even power your console on and off from the Spawn Player so you don’t waste energy.
    * If you are travelling, you and a friend can both play a game running on your console at home. You can each run the Spawn Player on your computer to play remotely in multi-player mode at the same time.
    * If you want to show your friends some tricks or moves you’ve learned in a game, you can have your friends use the Spawn Player in "watch" mode to watch you play a game on your console in real-time from their computer.

Or you could move the console and plug it in locally. Its an interesting idea but I dont see many buying it.
