I will check it out again, but my understanding was that DTLS is
essentially a binding of TLS for UDP, but does not change the
handshake semantics.

Do keep in mind that the ability to start sending data after the
client_hello by itself does not help, if the client_hello does not
contain all the information needed for the Server to authenticate the
client. So if the server responds with server_hello and then has to
wait for the client_finished, it may not really help (depending on
