IMHO this is a better idea for most glider pilots than a transponder might
be, it doesn't show all traffic, only those approaching with a transponder
on, but a transponder won't show you any and you are dependant on ATC
notifying you and the approaching traffic of your relative positions, it
won't signal an aircraft with TCAS that you are there but many of the close
calls will be with aircraft not equipped with TCAS anyway....

Will it work in the large areas of the western US where radar coverage
is spotty or nonexistent, since transponders don't transmit unless
interrogated?
