For LAC we use icecast2 servers and a `dvgrab | ffmpeg2theora | oggfwd`
pipeline to send an A/V stream to it.

http://en.flossmanuals.net/FFmpeg2Theora/StreamingDV/

For conference streaming: http://dvswitch.alioth.debian.org/wiki/

For more /artistic/ projects: Pd-extended features [oggamp~] [oggcast~]
[pdp_icedthe~] [pdp_theonice~]

gstreamer can also send A/V to icecast:
`gst-launch videotestsrc ! theoraenc ! oggmux ! shout2send ip=...
port=... password=... mount=/test.ogg`
or
`... theoraenc ! oggmux ! fdsink | oggfwd server port password -p -g
"genre" -n "title" -d "description" test.ogv`

VLC features built-in camera capture and icecast/shoutcast support. It's
also one of the few FLOSS projects that supports QT capture on OSX: vlc
qtcapture://
--sout='#transcode{vcodec=theo,vb=128}:standard{access=shout,mux=ogg,dst=source:ICECASTPassword@email-addr-hidden:port/mountpoint.ogg}'

In the not too distant future .webm will become a viable alternative,
but icecast2 does not yet support that OOTB on most distributions.
HTH,
