I don't know much about how RSS feeds are formatted. Looking at external.php it's obvious that it builds an xml document, but I don't know what the rules are. I suppose you could copy external.php and modify it (i.e. take a lot of stuff out and modify the part that actually builds the RSS2 feed). If you knew how to add your podcast info to a feed, you could probably stick a function call in external.php to add it to the feed it generates (and of course include the function somewhere - I guess you could do both with one php "include call"). There's just no way that I can see to do it with hooks.

Edit: around line 582 of external.php there's this:

PHP Code:

    $xml->close_group('image');
    if ($podcastinfo['subtitle'])
    {
        $xml->add_tag('itunes:subtitle', $podcastinfo['subtitle']);
    } 


Maybe if you change it to this:

PHP Code:

    $xml->close_group('image');
    include('mypodcastfeed.php');
    if ($podcastinfo['subtitle'])
    {
        $xml->add_tag('itunes:subtitle', $podcastinfo['subtitle']);
    } 


and in mypodcastfeed.php (or whatever you want to call it) get your podcast info from somewhere and build $podcastinfo[]. But I think that only allows one item, so maybe instead you can make the xml calls to add as many as you need, refering to the code in that section.
