I'm trying to create an app which instances itself and where each instance needs to register its existance with the others. I had assumed that multicast was the way, but I've had a lot of problems, particularly it seems i can't have two or more concurrent listeners on the same mcast-address and port number (the second bind fails). Is that a valid situation, or must I have done something wrong? And if it is valid that there may not exist multiple concurrent listeners on the same mcast-address/port, then how do my instances communicate?
