Probable dependencies: json: to serialize the transaction dictionary into a JSON formatted string; sha3: to hash the serialized transaction; and cryptoconditions: to create conditions and fulfillments

Steps:

1. Create key for Alice
2. Create key for Bob
3. Prepare Tx for Create Op
4. FulFill Tx for Create Op
5. Sent Tx for Create Op
6. Prepare Tx for Transfer Op
7. Fulfill Tx for Transfer Op
8. Sent Tx for Transfer Op

Rough goals:

• ease of use
• form tx struct, get json and/or protobuf
• driverhandles failover between nodes in a federation
• federation discovery using nslookup?
• maintain state?
• support the event API with a long-lived connection?
• https and http. spdy maybe?
• fast
• initial version handshake?
