I could not figure out how to make VLC transcode correctly to a bitrate lower than 64kb, or mono, no matter what the setting is. 24, 32, and 48 kb seem to be the sweet spots. Too low and packet drops lead to big dropouts in the audio. Too high and you get massive packet drops. I made mono files with 'lame -b 32 -m m in.mp3 out.mp3'. - Edit the 'bar' portion of config.sdl as necessary. - Stream a file in VLC with Media->Streaming, pick a file, click Stream.
