“But what about mandatory fitting of FLARM in gliders?”
Why limit it to gliders, why not go for mandatory FLARM in all aircraft which cannot fit Transponders, or even all of GA?

I would agree, but unfortunately that won't happen. The process of the CAA mandating something like FLARM would never happen in a million years, and if they did, the cost of having FLARM fitted would soar. Permit aircraft could probably be "forced" to fit FLARM by their regulator as part of the permit conditions - I don't know.
The point is that if some are forced, those who are sensible would buy the kit anyway. I would if by buying it I new I could avoid all gliders (in and out of IMC) and/or all non transponding aeroplanes.
