How's this as a hypothetical RSS module:

<rss:item>
   <rss:title>Ian's Bad Poem</rss:title>
   <encl:enclosure rdf:resource="http://example.com/torrent"
      dc:format="application/x-bittorrent"  <!-- whatever -->
      dc:title="Bit torrent link to mp3" />
   <encl:enclosure rdf:resource="http://example.com/mp3"
      dc:format="audio/mpeg"
      dc:title="MP3 of me reading my poem" />
   <encl:enclosure rdf:resource="http://example.com/text"
      dc:format="text/plain"
      dc:title="My poem itself" />
</rss:item>

Clients can choose to download the most appropriate format, either 
automatically or by presenting a series of links to the user with the 
titles supplied.

The encl:enclosure elements can be extended with any RDF properties. 
Some useful ones from Dublin Core include 'license', 'publisher', 
'audience'. MusicBrainz define some other interesting ones such as 
'duration' which could also add value.
