Yes, live sources do not use requests -- requests are typically files.
Therefore you don't see their track using requests.on_air.
What you should do is setup a on_metadata handler that keeps track of
the latest metadata seen on your source and register a telnet command
that returns this value. Something like:
meta = ref []
def seen(m) =
meta := m
end
s = on_metadata(seen, s)
(...)
def saw(_) =
"#{!meta}"
end
server.register("on_air", saw)
