Add support for the Sony NW MP3 walkmans
Submitted by Bastien Nocera
They support some hacked up version of MP3, AAC for some revisions of the firmware.
There's Java code to do it at: http://sourceforge.net/projects/nwe00xmp3man
and some C code (and an outdated gnome-vfs module!) at: http://www.waider.ie/hacks/workshop/c/mple/
and some sort of command-line tool: http://ubuntuforums.org/showthread.php?t=206470
Looks far from mature, but I guess that you need to start somewhere ;)
