enclosure rss?

hi …

those of you who like podcasts will know that the RSS spec (or the podcast-maffia, depending on view) does not allow multiple enclosures in one post. as it makes absolute sense for me though to have multiple files in one post (have a look at the page concerned: http://www.de-bug.de/pod/ ) and as i am far too bad in php (zero) i thought i might ask somebody to help me out building an rss feed for the enclosures only, with one enclosure per item, (querying wp-postmeta instead of wp-posts should do it). i know it’s not too difficult, but i just dont get it on my own.
