removing the user input from icedemo.c

[kaneda.uy@xxxxxxxxx (Andrés Suero)]

We created a randezvous server to interchange the SDP info of two 
clients that want to initiate an ICE session (icedemo.c).
We are removing the user input from the icedemo.c but we are having some 
difficulties, for some reason if we execute the functions without human 
interaction the SDP is not complete when we try to get it.

Is there some way to know when we have the complete SDP like some event 
or function result.

The idea is to call the functions like this:

         icedemo_destroy_instance();
         icedemo_init_session('a');
       icedemo_show_ice();
       icedemo_input_remote();
       icedemo_start_nego();

Thanks.
