 Hello, if I have understood you (because I have accidentally lose the
 2 first messages of the thread) you want implement a framework to
 manage media objects... 
  Have you seen the "CORBAtelecoms: Telecommunications Domain
 Specifications" published by the OMG, in particular, CORBA interfaces
 references stream control, flow control, streamendpoints control,
 etc... and all media-data uses sockets, i.e. the speed is very
  * In other approach the control is very complex, (QoS...)...
  * is dificult to add functionality (p.e. add more commands like
 rewind in a video_player with the minimum effort).
  * other times, somebody wants to use propietary protocols for
 control an data transfer. (this is transparent).
 with this approach you can implement a video-game, p.e. like passing
 my hero position to another player... with zero effort...
 I don't know how you have implemented your framework, but the corba
 approach is so good... noooo? :-)   
 And all under the OOP model...
 Saludos. Antonio.
