/**

 * @brief RPC based subcommands for the 'net' utility.
 *
 * This file should contain much of the functionality that used to
 * be found in rpcclient, execpt that the commands should change 
 * less often, and the fucntionality should be sane (the user is not 
 * expected to know a rid/sid before they conduct an operation etc.)
 *
 * @todo Perhaps eventually these should be split out into a number
 * of files, as this could get quite big.
