Just had a look at the new website.
I noticed that you now put SmartTV on the list of capable devices to play. Now that is also very cool. No more need for a PS or XBOX

Hell yea! This project is getting more intense every day.
That's from the website:

agree, having an app on the smart tv, plus controller would be perfect! you don't really need anything else, would be very simple that way
Ye, a really lightweight solution for gaming. Specially if you already have a smart TV with highspeed connection available.
If you would fine playkey from your tv's app store, you would definately be intrigued.
It seems to me a natural evolution, as the internet get faster and more available. There is also going to be the benefit of not having to update hardware to play the latest games. Looking forward to try this.
