Theres a another interesting thing Gabe said in his interview about the steam box,
Do you envision a Steam Box connecting to other screens outside the living room?
The Steam Box will also be a server. Any PC can serve multiple monitors, so over time, the next-generation (post-Kepler) you can have one GPU that’s serving up eight simultaeneous game calls. So you could have one PC and eight televisions and eight controllers and everybody getting great performance out of it. We’re used to having one monitor, or two monitors — now we’re saying let’s expand that a little bit.
Well that certainly helps solve the surround video setups in the future.
This is something I was sniffing around Sony as a R&D project many years ago. I wonder if MHL could make almost any device surround video possible now? Still needs setting up, a projector and a massive parabolic mirror however…
