Your post on the Cuban monetary system was interesting. With them having two types of monetary coin, maybe you could use the standard convertible peso as the mandatory method of currancy to be paid players. Since this peso is the one used by forgein tourists, you might have to have an exchange rate set to convert these monies and use those calculations for potential salary offerings, etc.
Until Cuba has sanctions lifted, maybe use the German exchange rate for their currancy? Please don't ask Ozzie for his advice on this thread.
