Another possibiility that struck me - the Sansa Fuze can play Ogg
Vorbis files as well as MP3.  Given those aren't encumbered with the
same sort of restrictions as MP3, I image it may be supported by the
installed ffmpeg (indeed, ffmpeg -codecs does show an entry for
libvorbis, while there's no libmp3lame listed).  Any chance of an
--aactoogg option for get_iplayer as well as the --aactomp3?
Also, is there a simple command-line I can use to effect a similar
conversion of the m4a files get_iplayer already downloaded?  Or should
I just install e.g. Sound Converter.
