I've read of a few people who are thinking of installing Pilotaware on the ground, say at a club base or even in the tower, for situational awareness.
It would need a Pilotaware box, mains power supply, iPad/Nexus tablet and SkyDemon/other charting app.
The standard build broadcasts position messages all the time but I would think that's unnecessary and even misleading for known static receivers.
So one possibility is that the system only broadcasts position when actually moving. Like some Mode-S transponders which only go active after takeoff (detecting speed from the GPS). Clubhouses would not then be see as potential collision risks as you come in on short final
The downside of that is that if you build a unit and want to test that it's transmitting, you have to fly. You can't check it onboard before take-off or in the clubhouse first.
So at the risk of being cheeky, I'd propose a good solution might be to make this configurable between "Always on" and "Only when moving" (default = always on). It still means that people could use one in their cars and cause potential false alarms if they chose to, but less of a risk.
Another simpler option is to set it to a code that is ignored (eg all zeros)
Perhaps not the most urgent feature to implement, but hopefully not in the too distant future.
What do others think?
