escrow service(ES) has bitcoin daemon and dwolla app registration.

client A tells ES it is willing to use ES for a transaction with client B, finishing in a given amount of time, and provides a dwolla address. (half-open state)

ES provides a transaction ID and a bitcoin address to client A.

client B provides transaction ID (received from client A) and a bitcoin address. ES provides a dwolla address.
