h1. UDP prototype h2. Goals * Make a program which will listen for multicast message. * It should be also able to send. User can type a message and all other peers will print it when it is sent. * Test it with some computers. h2. Qt and UDP multicast There is no support to UDP multicast in QT4.5 according this bug issue : http://www.qtsoftware.com/developer/task-tracker/index_html?method=entry&id=57952. An alternative is to use a broadcast address with _QHostAddress::Broadcast_. It will only work with IPv4. It's possible to use UDP multicast only with the low-level API. This solution is OS dependent and will not be accepted. For the moment the broadcast alternative will be used. h2. References * http://en.wikipedia.org/wiki/Multicast
