Startup Idea : Night out live clubs

11pm Friday or Saturday night.. You and your friends want to go out. What club to choose? It would help to see cameras entrance or inside of clubs in your city so you can see if it's overcrowded before you even step outside your home especially in winter. I don't think people call in advance to get in a club. I'm thinking about creating network of clubs with online streaming. Revenue model (Funding): maybe with small monthly fees from customers who want to see clubs or clubs itself as marketing model plus online advertising later? Issues: Is it legal? What kind of licence do you need in UK to record and stream other people while clubbing? I don't want a big brother.. Not all the clubs would accept.. Give me feedbacks pls
