The idea now is to create a wrapper for mpg123 to do controlled playback of files stored on this machine, and of files sent to it via scp.
This project has nothing to do with serving mp3 files over the web.
Well, I have had zero time to do anything with this! However, I have found that running mpg123 with a nice big buffer is a good idea:
mpg123 -b 8000 song.mp3
Since you will get no dropouts that way.
