It's a bit of a vague question but PlayIt Live can be used as a "central" playout system with remote (home office) system is posssible.
I wrote up a "proof of concept" a couple of years ago.
Features developed since then
(particularly "priority streams" https://docs.playitsoftware.com/PlayItLive/211/priority_streams_1.html)
have improved on some of the limitations I identified two years ago.
The essence of how it works is for the "home office system" to create a stream and the "studio" system to play the stream as a remote URL.
Priority streams makes that process more robust,
Good afternoon, I'm new to playit, is it possible to go live from the home office to the radio studio?
