Pre-alpha search engine - walk2web

So, what is a pre-alpha alternative search engine? walk2web has developed a nifty web application that allows you to "walk" from one web site -via links - to another. They are working on a Search Engine version which will allow you to query a search term, something like Quintura or KartOO, but that's not done yet; so I'm calling it "pre-alpha." (or Stealth Mode)
