[Freeswitch-users] Extending mod_esf

I’m looking to do multicast send and receive as a module, I’ve looked at mod_esf and also using gstreamer but a mod_portaudio style module would really help. Looking through this list, there have been a few mentions, and a mod_rtp_stream that was begun – I have time and money to put into this now, does anyone know of any projects that already add multicast RTP send and receive capabilities to FreeSWITCH rather than starting fresh?
