Coralize Enclosure Support

I run a podcast that pushes 150gb of bandwidth per month, mainly through audio enclosures. I really want to shift some of that bandwidth onto coral-cache, but I dont want to have to manually rewrite every one of the hundreds of enclosure urls on my site.

Wouldnt it be neat if I could switch on a feature that would automatically coralize all our enclosure URLs? It would be a simple checkbox. By switching the URL on, all RSS feeds would have the enclosure tag urls re-written to go via coral.
