Oh god lol. Greenscreen would be nice, but that is a little bit in the future yes ^_^

But of course it COULD be imlemented. But what is the actual need for it? Maybe i could do something like on "The Soup" where they have a mini tv to the right of the guy, and they put different images on there. Other then that i dont see the point?

But if anyone could give me a reason to i would open about it.
