Clone of Torrent Metasearch Engine

I need a website like [login to view URL] with the same functionality but without user registration. ## Deliverables If you or your team can make a solid clone of this website you're very welcome to post your bids and references. I need the site to be fast and lightweight as well as I need comments in the code for later fixes. It also need to validate with w3c standards, XHTML. I also prefer if the search results are presented with AJAX instead of a plain old page reload. Feel free to contact me with questions or proposals.
