The only significant reason to oppose such a proposal are the costs
involved. What is really needed is a concerted effort to come up with a
truely low cost transponder or ADS-B transmitter (~$200), so that it becomes
a no brainer to carry one on everything that flies.

Not quite. It also needs to:
- contain the equivalent of a PCAS receiver
- fit a single panel position (preferably 57mm like the Filser
and Microair mode-S transponders do)

In addition is should probably:
- be light (under 900 grams)
- have a low power requirement, ideally no more than a glider radio
but certainly under 600 mA average
