But what we want...
This first experience puts together people in Natal-Brazil and Miami-EUA watching the same program at the same time, so it´s possible!
It was implemented to run over the Java TV platform, so it runs in set-top boxes and digital TV sets
Here is a way to include people in the “information society”

Now our main goal is putting people together for cheering but we also can have people working or learning using the same idea.
