Is it possible to send a raw UDP packet directly from the browser to an ip/port?

I've been told WebRTC, in particular data channels, allow one to use UDP on the browser. From looking at some documentation, though, I wasn't able to determine how to do the simple task of sending a raw UDP packet to a specific IP/port (possibly of a server that isn't aware of web at all).

Is it possible, and if so, how?
