Event with 3 big projection screens. The screen in the center shows the camera/video production of what happens on stage, the screen to the left shows the english version of a powerpoint presentation while the screen to the right shows the norwegian version (in this case). The two different "language-versions" are running from two different computers, both placed with the rest of the technical equipment (not on stage). I need to be able to control both presentations (computers) simultaneously with a single remote from on stage, so that when I click "next slide", I get next slide in both languages. Any ideas? Hopefully there is a wireless solution, so that the speaker does not have to be located at the speaker stand for the whole presentation. Eventually, the reciever of the remote can be located somewhere on stage and extended via cat-5 to the computers so that problems with wireless interference is out of the issue.
