Bob, this is an excellent idea, and one that crossed my mind last week, though
for different reasons, which I will touch on.

One of the biggest problems for parrot mode down here is the number of people
who haven't quite worked out how it all works, and would be able to make real
contacts, if someone could direct the traffic for them.

The net control would have to perform a couple of functions:

1.  Traffic division - Splitting the masses up into callsign groupings,
regional divisions or station classes (HT/mobile/kW&beam, etc), so there's less
competition per cycle.

2.  Net Control - ensure everyone conforms to the required protocol, which is
really dictated by the cycles of the bird itself.  Net control would also
involve a bit of Elmering to new satellite ops. :-)

Also, I feel it would be of advantage is the net control had (by virtue of
being in a valley, high gain antennas, isolation) direct coverage to as few
stations as possible.  Being within simplex range confuses some operators
unfamiliar with simplex repeaters.

It is a way to make it work for everyone, and certainly better than chaos. :)
