Since the Stack Overflow data dump will occur monthy, it makes sense to be able to be notified about a new dump and download it. The current solution has been to post a link to the .torrent file on the blog, but this process requires manual intervention on the part of the producer and consumer of the data.
A better solution would be to create an RSS feed that would automatically be updated after the end of every month. Many BitTorrent clients have the ability to automatically download from an RSS feed, which would be convenient for obtaining the latest dump automatically. I imagine a situation where as soon as a month is over a script runs on Stack Overflow to dump the data, compress it, create the .torrent, update the RSS feed. Within minutes users/servers across the world automatically see that there's an update and proceed to download, effortlessly creating a worldwide content distribution network.
To get started, here's a site that describes how to create a valid BitTorrent RSS feed.
