SDMI is a supposedly secure Digital Music format based on MP3. I am not sure
of technical details but I gather it'll be a key encoded file system. i.e.
Every MP3 Player has it's own key, when you buy a track in SDMI format it is
encoded for your key only, hence it is a one file for one player sort of a
deal. The actual encoding is still MP3 I gather they're basically PGPing the
MP3 file.

Not sure if it's taking off, winamp supports it. I heard that the record
labels that came up with it were trying to force diamond (and others) to
support it as well AND to allow a system whereby MP3 support could be
disabled either at a set date or when it recieves a certain signal (whioch
you'd get when downloading tracks to it I assume). Don't know where that
went, last I heard most people in the scene were still ROFL.
