It doesn't look like you can, with mutagen. So, time to find a different
library that supports arbitrary file objects instead of only file paths.
I'd suggest starting here:
http://pypi.python.org/pypi?%3Aaction=search&term=id3&submit=search

Possibly one with actual documentation, since that would also be a step
up from mutagen.
