2 - FLARM, due to its light weight and low power output is not detectable at significant range
3 - Gliders must be hit by Cat even less than they are by smaller powered aircraft, and even if you know the CAT is there, it is still the glider that needs to maneuver.
However, it does show what could be done with ADS-B and gives some confidence that in the coming years this issue will be resolved.
