vnc2swf doesn't currently support streaming and I suspect it would be
hard to add it...

You could also try looking at using vlc to do this though
(http://www.videolan.org) - they support live streaming and conversion
between different formats. The difficulty is probably mixing the audio
in with the video
There is a screencasting capability  and audio input is handled as well
(although I haven't managed to get them multiplexing together yet). But
may be worth having a look. You use their scripting capability through
something called vlm to issue statements like this (this example is
meant to transcode to a file)

new channel1 broadcast enabled
setup channel1 input "screen://"
setup channel1 output #duplicate{dst=mosaic-bridge{id=1,height=144,width=180},select=video,dst=bridge-out{id=1},select=audio}
new channel2 broadcast enabled
setup channel2 input "dshow://"
setup channel2 output #duplicate{dst=mosaic-bridge{id=2,height=144,width=180},select=video,dst=bridge-out{id=2},select=audio}
new background broadcast enabled
setup background input "fake:"
setup background output #transcode{vcodec=mp4v,vb=1024,scale=1,acodec=mpga,ab=192,channels=2}:bridge-in{delay=400,id-offset=100}:duplicate{dst=std{access=file,mux=ts,dst="c:\\Temp\\test3.mpeg"}}
control background play
control channel1 play
control channel2 play
