Yeah, but the OP is more like the "all you have to do is rsync and cron job". It's an article about the relatively complex step by step process that people do to implement a functionality. It may be the inspiration for an analogous dropbox, but definitely not the dropbox article or post. A product that you could grab from the app store that does all of this out of the box would be the analogue to dropbox.
That said, this would be interesting to someone who didn't know these tools could be stitched together in this way. I think that's a big part of why it's on the home page.
