Hi Ross,

Thank you for your patience and quick response. I will have a closer 
look at the proxy server code. However, this program (and others, like 
the testOnDemandRTSPServer) are creating ServerMediaSessions at startup. 
In my case I do not know which streams will be used at startup. I will 
receive a clients request (from network A) at runtime and than have to 
setup the connection. Furthermore, when nobody is interested anymore in 
the (unicast) stream, I have to close it to save bandwidth (at network 
B). Could you point me a little more in the correct direction? Do I have 
to make my own RTSPServer object (derived from the original)?

Thanks in advace.
