[Freeswitch-users] One to many w/o mod_conference

Greetings all,
I have an application where I could use some expert advice. I'd like to set
up an audio broadcast bridge, where the audio from one call would be
distributed to multiple listeners. Listeners have no send audio. Think a
corporate conference call with only one host. All listener calls are
I could of course set this up with mod_conference and just mute all the
listeners. But this requires a bit of overhead to convert everything to PCM
then back to the listener's codecs individually. I'm working on a
resource-strained embedded system, so I'd like to find a way to simply
bridge the speaker audio to multiple endpoints simultaneously. I have very
tight control over the codecs used, and can make sure they are all the
same.  Sort of like live MOH (I'd be using mod_portaudio for the sending
endpoint in fact). Delay must be very low, so converting to a shoutcast
stream and using the MOH function isn't an option either.
Can anyone offer any advice? Maybe FS is just not suited to this?
