All info required to configure client to receive streams is already in 
SDP (in my case or in case of applications similar to mine, see Helix 
Mobile Producer for example)

Before starting to encode my application is configured with destination 
IP, port and ttl. This info is saved into SDP for clients.

In my specific case using separate Darwin server is better.
Just two reasons:
a) customer is paying for this
b) there is pre-built network with already configured and tested 
streaming servers. Why to change something there? My solution does not 
affect anything in network configuration, especially security issues.
