In a podcast feed, the enclosure URL points back to cdn.castos.com. Would like to have the ability for it to point to a custom domain (podcast.podcastwebsite.com) for example. This would serve two purposes:
1. Have a permanent link for the audio URL. Useful in case you need to change hosts or whatever, can simply maintain the same URL or have a redirect.
2. SEO linking for embedded players on other websites. Instead of all these sites linking back to a CDN, if they link back to your domain your SEO rating goes up bigtime.
