This is my apologize to Charly - he is right in many aspects.I had a pleasure to talk to supervisor of tech support and tech solutions of this project yesterday and have to say - its really some unique idea.Its really working insane in beta-testing and its really about huge investments.Anyway I think its possible to copy that idea in few months - just a matter of money.
