Is it real or is it Memorex?

I'm curious what everyone thinks about podfic's status as a fanactivity. Do you think about it as an independent work of art itself, or is it a way of offering additional accessibility for fanfiction? How does it compare to other fanactivity which depends on other fanactivity like recs, archiving, challenge-running, com or listmodding? How does it compare to other fanactivity which can work with just canon [or even be totally original], like art, icons, vids, fanfiction, or costuming?
