I've done live presentations with many different speakers. I use two computers to show presentations and switch between them (using the VGA switch) as they queue for the next speaker. My problem was using a single clicker for presentations. If I were to use two clickers there would certainly be confusion as to which would be the 'active' so I didn't want to create that script. I was able to use two broadcasters (one on each computer), but clicking the Next button meant I couldn't queue up the next speaker's presentation without moving on. I bought it in the hope that I could "share" a transmitter and just choose which computer I want to use it on. It worked so well that I'll buy another one if this one breaks. I'm very glad this is a "sharing" switch and not just for printers.
