Under normal operation, everyone on frequency can copy beacons and CQs. When 2 stations are connected, copying everything being said can be problematic. But beacons and CQ usually are decoded. This got me to thinking.
If there were a special setup within Settings (ala WSJT-X "Advanced Settings") where instead of having windows for becons and CQs there would be (by way of the special setting) windows for check-ins and Net Control (NCS) for a WAS Net, ARES Net, etc. When NCS announces preambles and calls for check-in, those messages could be decoded in the existing Data Stream window. Or maybe in the VARA monitor window. Because of VARAs 'busy' feature, when NCS calls for check-ins, all stations can hit the 'Check In' button and the program will sort out pile-up. When NCS gives a net member a turn to call a station he heard, they could 'connect', pass data, disconnect and pass back to NCS. Unless operating on FM or in GREAT band conditions, not all net members will hear the connected QSOs but as long as they can connect to their desired contact or NCS, messages will get through.
I'm not smart enough to think of all of the details, but it is a concept. But imagine a large number of operators existing on the same frequency participating in the same event.
