Answer 1

If you're using C++, I'd recommend using the Boost ASIO package for networking. The only gotcha is to be sure to set the broadcast ability on your UDP socket via:

boost::asio::socket_base::broadcast option(true);
socket.set_option(option);

The "Examples" section of the boost documentation should have plenty of references to get you up and running.
