RSS to email and back

In the last couple of weeks I’ve come across more than a few articles concerning various ways to get RSS feeds by email (this being the latest). I can see why they want that but personnally, I’d like to have the opposite, a mailbox that I’d get as an RSS feed, that way I could set up a seperate email that I would subscribe to various alerts or lists and get them with all my other news in NetNewsWire. Can’t be that hard to do and I’ve seen a few pieces of code that could make it happen, anyone seen something complete?
