Sort of.  My vote would be for the 'periodic GPS data burst' method which would give
all the data to the pilot and put collision avoidance responsibility back in the
cockpit (WITH, of course, the data necessary to MEET the responsibility).  At this
point, the responsibility of the FAA would be to listen to the data bursts, map them
to radar targets, skin-paint the non-players and generate 'virtual' data bursts FOR
them.  That way, the players (most of us) would have the required data on everyone
including the non-players.  Software with standardized 'threat resolution logic' and
protocol could notify players of 'contention' and recommend an avoidance procedure
compatible with the similar procedure being recommended to the other guy by his
software.  When 'contention' escalates to a 'threat' and evasive action is necessary,
it is very important that all of the 'players' be making compatible 'moves'.  All of
the software here could be a feature of moving map and GPS navigation software, and
thus would not represent 'extra' expense.  The transceiver cost should come down
dramatically (sort of like GPS did from '90 to '95) as usage increases.  The beauty of
the thing IMO is that the FAA's responsibility consists ONLY of making 'semi players'
out of non-players by broadcasting pseudo bursts FOR them into the 'system' and would
diminish as more non-players became equipped.  Transceiver could even become a feature
of the GPS itself.
Just a theory ...  Jim S.
