Even though the idea seems a little crazy I think it`s possible to organize such a event. There are couple of hey things that have to be taken care of: -cheating ( by announcing a topic couple hours before event starts ) -getting media sponsors ( preferably startups with API' ) -presentations streamed ( justin.tv/ustream etc.) -progress written up ( like http://www.travisglines.com/web-coding/lets-make-a-twitter-clone-in-node-js http://www.travisglines.com/web-coding/lets-make-a-twitter-c...) -possible prizes via AppSumo or similar venue I`ve been actually thinking about putting together such a event in the next couple of weeks. Since I`m launching a website in exactly that area soon, check it out in my profile.
