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.
