The ADS-B system proposed will also not supply the Ag pilot any way to 'see' the RFD aircraft.
that's not absolutely true.
If,
one, of the aircraft has ADSB-IN (most likely the RFDS in this case), then that aircraft could independantly manouver out of harms way., even when out of range of an ADSB base-station, and all without ATS even knowing what is happening.
