scenario:
- name server starts and starts looking for other name servers. Creates
  and maintains cache list of name-servers and servers registerd with
  name-servers
- server registers with name-server. name-server broadcasts change.
- client starts and sends request for available name-servers and servers
- retrieves cache list of server that first replies to it and uses its
  IOR or request for server with special name. 
  e.g. propagates list to user in GUI like:
  rmr-name-server
  |--> rmr-server
  |----|--> rmr-page
  |----|--> rmr-object
  |----|--> ffmpeg-object
  in-transit-name-server
  |--> video-server
  |----|--> ffmpeg-object
  |----|--> ...
  |--> 3d-server
  |----|--> opengl-object
  |----|--> ffmpeg-receive-object

Something like that?

Think this should be customizable in some sense (maybe just on/off) as
it is not always welcome to now all servers. If just running standalone
installation you may only want to know local name servers and spare the
network overhead.
