h1. UDP prototype
h2. Goals
* Make a program which will listen for multicast message.
* Test with some sub-networks.
* 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.
