FB interfacing for CL clone (e.g. Locazolist)

Facebook application interfacing for craigslist-type classified ad site. Create a facebook profile application that lists the users "for sale" ads as posted on the main application site. Classified site can be a purchased craigslist clone (like Locazolist) with a front-end for facebook if it is possible to implement full functionality without violating terms of use. Otherwise classified ad software would need to be built as [login to view URL] site is limited to 'for sale' items only, segregated by the user's geographic locale (similar to craigslist). Users on facebook can view ads posted by friends from facebook profile page, search for other sale ads from the profile box, or start process of posting own add. Add posts trigger not only update for profile box but also mini- and news feeds describing new ad. ## Deliverables user experience is as follows: from facebook, user sees news feed regarding friend's item for sale OR user sees item for sale on profile box of friend's page. clicking the link brings user to that item for sale on classified site (modeled as facebook app). user can ask seller questions or make offer using facebook messaging, etc. transaction may then occur online through paypal or other alternative payments, or may occur offline. following transaction seller may remove listing and it will disappear from seller's profile box. from seller's profile box, user can see items listed by seller (as above), links are also available to start new posting of user's own or search classifieds in relevant geographic area. if user selects to post his own time for sale, he will be asked to install the facebook application. 'registration' of new app user will include gathering of data such as relevant geographic market (to be used for searches from that user's new profile box). normal craigslist-like posting environment follows (including photo upload, etc.), with feeds to fb mini- and news feeds as well as updates to user's profile box reflecting description of item and image if applicable. if user elects to search for other listings from profile box, user will be directed to search results in main app page for the geographic region of the seller. only 'for sale' categories will be relevant.
