Interesting, I am DevOping right now a ETH based set of derivative futures options SCs, utilizing ORACLIZE and Piper's ethereum alarm-clock functionality to wake up a SC. With a full state machine nature and a counter-party to each SC for minimum of 100ETH per put or call 'bet' on a ETH USD$ price - ORACLIZE pulled in from C/base.
SC will have strike price and expiration dates and auto state re-set, full fallback capacity with re-entrancy guards, perhaps fully audited- TBD. following EEA and consensys best code/ patterns practices.
