Creating XML/RSS enclosures in Drupal for file attachments

"Podcasting" (a.k.a. Personal Option digital, a.k.a. audio blogging) is to radio and other multimedia as blogging is to text. It would be a simple matter to enable Drupal to play a role in this exploding desktop audio publishing phenomenon.

Version 2 of the RSS specification allows for the RSS/XML feeds to contain "enclosures", which are simple XML code elements that point to downloadable files on the net. In Drupal it is possible to attach/associate files to nodes. How difficult could it be to generating RSS/XML feeds with enclosures that point to these attached files?

The use of these enclosures promises to dramatically facilitate distribution and aggregation of multimedia content. People will be able to customise and control and comment on the audio content passing through their blogs the same way that they currently do with text.

This would be a simple and yet powerful addition to the Drupal feature set that I think would have positive viral reprocussions inside and outside the Drupal community.

I welcome any advice, feedback and/or offers of help.
