// creating and monitoring accounts, creating transactions, and so on
// should use this interface. The RPC code will primarily be a light wrapper
// over this code.
 
// Eventually, it will check the node's operating mode (synched, unsynched,
// etectera) and defer to the correct means of processing. The current
// code assumes this node is synched (and will continue to do so until
// there's a functional network.
