A colleague and I decided to "share the hobby" at work recently, and we used FPV Freerider Recharged along with a couple pairs of DomV3s.
My Doms were set up so people could look through an actual quad's FPV goggles if they wanted, where as my friends were hooked up to the computer. We had a spare monitor hooked up mirroring the goggles so that spectators could see how the person was doing.
It worked fantastic.
