I want to have an app built to use in Facebook. I want the app to create custom tabs in our customers' Facebook Pages which embed their chosen web page (from their own website) into the Facebook tab. For example, in a Real Estate agent's Facebook Page, click on the TAB 'Homes for Sale', you then see the 'Homes for Sale' web page embedded in their Facebook Page. The content should behave as their website does, scrolling and searching for houses etc. I want to then be able to offer this App to Real Estate customers to embed their Sales listings on their facebook page.
