I've already talk a little about it on IRC.
It's for an old unix' console player : mp3blaster.
In fact, I have a file server who's connected to my audio system. And I was looking for a console player to play my mpc.
After some search, I've decided to code some plugin for mp3blaster
My code is a litle bit hugly, and there's no recognition of apev2 tag nor id3v2, but i can share it if someone is interested
NB: a complete recompilation of mp3blaster is needed to add the mpc reading capability
