docs: This method is called by the JFap channel to give us the oppurtunity to specify which thread
  the receive listener should dispatch the data on.
  <p>
  In this instance, we do not want to do anything special here, so returning null indicates to
  the JFap channel that dispatching should be done on a per conversation basis.
  
  @param conversation The conversation the data is about to be dispatched on.
  @param data The data about to be dispatched.
  @param segmentType The segment type of the data.
  
  @return Returns null.
