Hmm, no, I didn't want to go the dirty way of having to rename the tracked songs to MP3s.

I was referring to the rumours of the player software on Empeg getting support for plugins (sometime). This would easily allow for new file types:

-> (3rd party) software to support new files ships with a detection plugin for emplode. Emplode, when accepting files through drap&drop or however, runs through its detection plugins to figure out if the file type is accepted
-> On Empeg, the same thing will happen, just that there's also a player-plugin that will handle the playback of the song

This should be pretty easy to do, the plugins really only need detect() and get_song_info() to return ID3-style information.
