I've actually never seen this. Looks very nice. The idea of mine was also to keep the same API (the HTML and the links schema) of HN, to enable re-use of already built crawlers and add-ons. Also, this seems to depend on Ruby other than Redis. Which means you probably need to buy a VPS or some cloud hosting and set it all up with Redis and Ruby and other stuff. Lots of overhead if you ask me. While with hckr.it, you simply push it to a Couch and you're done.
