Spawn Labs lets you play your console games like you were at home, on the road, just via an internet based computer. You plug in an appliance to the console, and then to the internet. Install the software on your computer, and voila, you are gaming in 720p, at 30 frames per second.
The software is very slick in and of itself, allowing you to view multiple consoles, what game is loaded and the like. You can even have several players in the same game on the same console, all remotely. Also, you can record and replay game sessions with your friends, allowing you to relive the pwnage again, and again, and again.
Rub it long, rub it in hard, rub it in remotely.

The initial cost is high, but for the travelling gamer, it might just make the worlds best Christmas present.
