Integration with emaudio?

I just came upon this module, looks (nearly) perfect for a site I'm in the middle of building. However... ;)

The site I'm working on is really an A/V index. We're not hosting all the files locally, just creating nodes and nice ways to search/filter/sort/feature etc. The actual audio files live elsewhere (for bandwidth/disk reasons), so my audio nodes use an emaudio field, not a filefield. It seems like it should still be possible to create a podcast feed of nodes with an emaudio field, right? I mean, technically, it shouldn't matter what path to the mp3 file is included in the XML for the feed. But, it doesn't look like there's any way to configure the itunes.module to know about emaudio fields for certain node types at admin/settings/itunes.

Seems like this should be relatively trivial to get working, right? I don't see any issues that mention emaudio currently in the queue -- I'm a bit surprised no one else is trying to do something like this. Is that because I don't understand something fundamental that's going to make my life miserable if I continue down this path? ;)

@drewish: Would you be willing to add such functionality and support both filefield and emaudio fields if I were to get this working? Are you at all available to help me get it working? ;)

Thanks!
