Its possible to go through a series of steps when establishing a connection, to see what is possible. For example the client could firstly attempt a plain bidirectional TCP connection, if this fails, try the next approach etc, etc. Obviously if you know in advance that only a certain type of connection will be possible then that could be specified, perhaps as a parameter for the "connectToServer" method or simiar.
