My only excellent restaurant experience was using the Roger Pen, which Steve Sells networked.  Each one of us had our Roger Pen hanging around our neck, while we ate lunch. And we could hear each other loud and clear -- even though there was tremendous background noise going on.

I am wondering if you know of a clip-on mic that could do the same thing. I only know of 1 to 1 clip-on mics. That means you can communicate with just 1 person at a time. Does anyone make a clip-on mic that can be networked?
