The simplest (and yet apparently hardest) thing would be for the hold-out to stop holding out, drop their lawsuits and allow the insurance company to pay out the proceeds. Second would be for the courts to rule in the Owners' favor (this has been an ongoing process for years; unfortunately the court system is typically slow), and finally maybe if some laws regarding homeowner ship and co-op rules to change (which might move the previous legal process along faster).

I suppose if someone were to win the lottery they could always front the owners the funds. I got my Powerball ticket already!
