  14
  15 This is the jabber connection where all incoming client requests will be accepted.
  16 This connection takes the data, passes it off to the system then returns to take
  17 more data.  Connection params are all taken from the config file and the values
  18 retreived are based on the $app name passed into new().
  19
  20 This service should be loaded at system startup.
