I don't think it works quite like that.  AtomicParsley puts the ID3 frames inside ID32 atoms in the MP4 tree.  iTunes ignores them - are there other media managers/players that can read those frames?  More esoteric is the fact that atomicparsley apparently only writes ID3v2.4 frames.  I would guess that any app that could read ID3 frames from MP4 trees would also do ID3v2.4, but I have no real clue.

A configuration mechanism is a good idea, but I think it will have be based a full mapping of get_iplayer fields -> MP3 frames -> MP4 atoms.  I've done this for iTunes, and it's pretty straightforward.  I don't think id3v2 can add artwork, but that seems  acceptable unless someone knows of another cross-platform ID3v2 command-line tagger that can insert APIC frames.  The alternative would be come up with some sort of integrated tagging plugin, but I'm not sure it's worth the bother.  I've been using mutagen, so I don't know whether the available perl modules are even up to the task.
