Idea factory: TV show chat room

So the idea is to have a discussion portal while you are watching a TV show. For eg. you were seeing the Democratic convention and wanted to discuss what Mrs. Obama was wearing. What better way to get on a forum discussing the convention and maybe join a subset room (there may be a political room, a fashion room) and you post your thoughts, get feedback, maybe find out where she got that dress and get one for yourself! Make a note, save it, or go online and shop for it right then and there! I'm looking at this as a potential Apple Iphone app.
