Beverly Hills Hotel participates in the Ripple network and issues its USD-denominated IOUs which are redeemable for hotel stays.
Beverly Hills Performance Car Rentals participates in Ripple network and issues its USD-denominated IOUs redeemable for car rentals.
Both the hotel and the car rental shop have unrented inventory.
Daily room rental rate in USD is roughly the same as the daily rate to rent a Ferrari.
Question:
Can the hotel owner and the owner of the car rental business exchange their respective IOUs through either a mutually trusted gateway/nexus or directly (assuming they trust each other) or through a web of trust to allow a room to be rented out for a day of stay and a Ferrari rented out for a day of driving ?
Bonus question:
Is this the real purpose of the "issuer" field in the current Ripple user interface, i.e. to allow any participant to issue IOUs denominated in any currency of their choice ?
