Demo uses STREAM socket when it should be using DGRAM

[matthew798]

This demo is incorrect. It uses Stream sockets for DTLS which completely defeats the purpose of DTLS and negates any performance benefits of UDP. In fact, you now have 2 layers of reliability; The TCP stack and the built-in "reliability" of DTLS. People should definitely not be using this demo as an example of what to do.

I'm surprised it even worked. If it ever did...
