We may not have to wait 10-20 years. The new MITRE low cost ADS-B
transceiver (transmitting your location, while also receiving traffic &
weather data) should be in testing this fall. The last I heard, they
already have a couple of companies lined up to license the design for
commercial production.

Just installed and certified a transponder in the new flying
machine, too. But this is old technology. When we all have
transponders it will drive ATC crazy with gaggles of proximity alarms
going off.

That can be handled with an assigned code like the 0440 used in Reno for
gliders. The software can be instructed to ignore conflicts between 0440
codes, which, I believe, is what is done in Reno. There may be other
methods they can already use, especially if the glider density is lower
than Reno.

Be better if every aircraft had FLARM.

We will, in 10 to 20 years, but we'll likely call it ADSB. FLARM, as
presently implemented, probably wouldn't appeal to 250+ knot airliners,
because it's range is too small. I think it's better to work for a low
cost, low power, ADSB with modest features like the Mitre unit.
