I don't know about the relay pull stuff but we do the same thing of
switching from prerecorded content (in our case, rebroadcasts of our
live show from last week) to the live show.
I have one icecast server setup with ices streaming the rebroadcasts.
When it is almost time for the live show, I start oddcast with the live
feed and connect it to the server. At this point, the icecast server has
two sources each with different mount points. When we want to go live, I
kill ices and all of the existing listeners get moved over to the live
