Because I consider it bad form to expend funds and NOT fix obvious
flaws simply because present day voice has a similar problem (albeit to
a lesser degree).

I agree, which is why I said "similar to ADS-B" rather than ADS-B itself
in the original message. http://www.airsport-corp.com/adsb2.htm has
many issues presented with regard to ADS-B. The technology we actually
use should address the issues presented in that document.

Even something like tracking a specific aircraft's movements should be
addressed. We are already seeing places using services like Flightaware
to track their competition's movements on IFR flights, utilizing it as
a type of corporate espionage. I see no reason a transponder or ADS-B
needs to identify a specific plane, just that there is a plane in a
particular part of the airspace so other aircraft avoid that spot. If a
particular plane needs to be intercepted for a legal purpose, that can
already be done.
