I started two piece of MyServiceProvider by manipulating the rtc.conf between starts, to make them different console windows. In the original setup the MyServiceConsumer called functions only one of the connected MyServiceProviders. With the modified source code (applying the method mentioned before) The Consumer call functions on all Provider (or we can choose Provider from the map by connector_id as well).</div>

Those port are CorbaPort-s, "X" marked are holding Consumer and "O" marked are holding Provider of an interface, having one getter and one setter function. The component on the right (PoC_VirCA) is supposed to provide information for every other component by getters (it does), and utilize setter functions of connected components, thus update their state. But only if needed! We want to update only "subscribed" components, so want to define which active connection should be used for updating.</div>

<br></div><div style="font-family:verdana,sans-serif;font-size:small;color:rgb(0,0,0)">Meanwhile, we have further experimental setups, which shows, that we can address providers, but it's a bit complicated. We defined ConnectionListener for the Consumer and when "on connected" call-back function is called, we store a copy(!) of the Consumer in an std::map, using the connection_id for key value. Later, we can use this map (containing copies of the same Consumer) for calling functions on specified connections.</div>
