ajax breaking news CMS - coding ( not design )

I need to build an Ajax based system that automatically posts latest news/posts based on predefined keywords. Similar concept as [login to view URL] ( see attached jpg ) Based on a search term entered in the backend - nesws/blogposts will be automatically posted in the site. the system needs to be built in a way that can easily be reinstalled in different sites. it can be built on CakePHP ; [login to view URL]; rubyonrails; symfony; CodeIgniter. 1. Design will be provided 2. Functionality : Similar format as [login to view URL] - - Images also need to be included in the headline posts. - Frame - once clicked on the title and redirected to the news source - FRAME will appear on top of site ( ex: [login to view URL] ) - dynamic adsense fields in backend - automatically generated Hot Topics ( based on user interest ) - automatically generated Hot Topics ( based on user interest ) - news filter ( see [login to view URL] - filter on left side ) - Follow in Twitter and Facebook login options - comments thanks
