Fast, Free, 4-Player Buzzer System
All you need to do is get the new PickMeBuzzer app from the iTunes store and download a "client" app for your PC or Mac from the buzzers.com site. The client app receives the buzz-in signals from your iPad/iPhone/iPod Touch and communicates who buzzed in first to Game Show Presenter.
The PickMeBuzzer is a great innovation by Groupics, the company behind buzzers.com. It works by having your iPhone/iPod on the same WiFi network as the PC or Mac running the client software.
The PickMeBuzzer is flexible. You can use it in the free, "Pocket 4 Player Buzzer System" mode as shown in the picture here. But if you have multiple players who each have iPad/iPhone/iPod Touches, then you can take it to the next level and let each individual buzz-in from his own device. (As with most apps, there's some fee involved if you use the advanced capabilities.)
In the free "Pocket 4 Player Buzzer System" mode, you just need one i-gizmo, which you would set on a table in the middle of your four (or less) players. Then they can buzz in by pressing the red button with their player number on it. The client side program runs in the background on your PC or Mac so it can pass through the buzzer info. to Game Show Presenter.
