It's a simple DTLS server, implemented with QUdpSocket, QDtlsClientVerifier and QDtls. The server is configured to use PSK only (it has no certificate/key). The server uses a single QUdpSocket socket and de-multiplexes UDP datagrams internally (thus it can work with several clients simultaneously). Future update will probably add more options (like configuring with certificate/key, etc). For now - it's as minimalistic and simple as possible.
