My explanation was not as clear as it should have been - please accept my  
apologies for that. The client that I described does not display media and  
does not send or receive media streams. It is the server that will  
render/display media, and it is up to the server to work out what media is  
available to it and to arrange to stream (or otherwise obtain) it. This  
aspect would be completely opaque to this client. The server/renderer  
could well use DLNA to discover and stream that content from a 3rd device,  
but the client would not be aware of this.

For me, the attraction of this model is that it is more abstract that just  
streaming and can easily subsume access to local storage but also access  
to services such as live television broadcast. A television programme is  
just another item of content that the server reports it has available to  
it, and which the client can ask it to display.
