This sounds as though it'd have the problem of allowing a normal user to
overwrite an arbitrary file (possibly including /dev/hda) with an WAV
file produced by ogg123, and also to read any Ogg file owned by other
users regardless of file permissions.  Ideally you'd want a setuid
wrapper which bumped up its scheduling priority, gave up root
priviledges, and forked ogg123.

On the other hand, for a single user system in which the administrator
is really the user anyway, it would probably be fine.

Cheers,

Cameron.
