Agree with what some have said about a partnership being tough. Just look at the current state of the economy to see how many businesses/partnerships have gone under and most of these had the opportunity to generate revenue. Only way I would possibly do it is if everyone was in with cash money. No loans. I would also shy away from any "guaranteed" buyback as life and financial circumstances will put people in a place where they can't afford the buyback and the guy that needs out will either default or be soured to the whole deal.
