While I was Chief Engineer at WCFI-LP, Anthony "Atrain" Messina would occasionally do a live 2 hour show on Sunday from Hadden Heights, New Jersey. We did this using TeamSpeak and it works great! Anthony has a recorded show that runs every evening at 11 pm.
I retired from the City's employ but I'm still helping with the station and periodically broadcast a show, The Italian Connection, live from my home studio.
So this idea can definitely work. Lefty can originate the live show in his studio. Users can then broadcast the show live on their stations as well as it being broadcast live on WCFI-LP. This would be a one-way stream, Lefty sending and everyone else receiving.
It would also be possible to do a multi-host program. A protocol would have to be followed to avoid feedback, echo and other problems.
A topic to discuss at the TeamSpeak meeting this Saturday, March 21, 2020.
