It occured to me today to wonder what revenue streams or business models could be copied and the answer was surprising.Mikey boy heres an early christmass present.
First off if you are going to copy, copy somebody smart, and just about the smartest guy on the planet at this stuff is steve jobs as he is both an apple and a disney boss. If like me you've got a kid you probably know about club penguin a disney portal that children can enjpy free but get enhanced benefits from subscription payment. Basically they kit out a penguin and an igloo with household stuff that they are able to buy with points they earn.This achieves status amongst their peers and a sence of achievment as they deck out the igloo with all the latest gadgets.
So using this as the analogy ciu could offer a virtual wc round business where you have to biuld a customer base, obtain a system, and operate in a virtual system and are able to compete against other window cleaners for market share. Some might go the virtual franchise route, others get a few vans on the road. There will always be the slackers of course who will work three days a week and think that's enough.
