GnomeVFS-plugin
===============

* We could have ssdp daemon (for maintaining info of discovered 
  devices/services, simple USN => ssdppacket mapping should be enough)
  
  This would be general solution, which would fasten the "startup-time"
  for upnpav-module (as deviced are already searched and discovered and 
  the results are fetched locally)

OR 

* We could have mediaserver client, which maintains info of discovered 
  mediaservers and their content. All upnpav-module instances would 
  query this server for contents of the given directory through DBUS.

  DBUS auto-activation could be used, so that the client would be 
  automatically started. There could be a timeout for the client to 
  quit.
