Cleanfeed.net is a service providing low-latency, high-quality two-way audio for podcasts and interviews using a web browser. I'm picturing running a Cleanfeed browser instance on the same computer as PlayIt Live as the source for microphone PTT, which would allow a remote announcer the ability to go live (assuming they were also connected by VNC or remote desktop for screen control). But this would require PiL to provide a mix-minus return feed (all the live-assist output audio sources minus the remote announcer via Cleanfeed) so the remote announcer would not hear an echo while speaking.
