  /*
   * !!!!!!!!!!!!!!! !!!!!! Test with notebook as server (esp. video things
   * and fullscreen switches (preferred using tv as monitor like the beamer))
   * !!!!!!!!!!!!!!!
   *
   * DONE 1 Add proper serialization (properties are good, but serialize the
   * media and ticker elts and so on too) DONE 2 Check all TODOS DONE 3 next
   * exception handling DONE 4 reconnecting with a timer -> see todo reconnect
   * in clientmsghandler
   *
   * DONE add handling for further prefs like changing fonts and colors of
   * live ticker
   *
   * DONE Use Command line lib like: http://jewelcli.lexicalscope.com
   * http://pholser.github.io/jopt-simple/
   *
   * Use Installer lib like IzPack
   *
   * DONE pimp the live ticker a little slightly transparent overlay or
   * something like that next pimp server gui (Effects and so on)
   *
   * Advanced/Alternative themeslide creator using templates or something like
   * that
   *
   * check for already running server instances, and esp. get a port from the
   * os not fixed (scanning the network for the server is required then)
   *
   * pimp the client gui -> resizable areas, event log, loading dialogs during
   * network operations
   *
   * next check all the image to imageicon conversions and choose best for
   * performance and RAM usage
   *
   * show once funktion z.b. für countdown oder videos
   *
   * next proper login handling (also to see which user did what and when) and
   * maybe the possibility to send messages or notes or something like that
