Support for Steam Broadcasting
Hey boys and girls, 
Recently jumped ship over to streamlink and was wondering if you guys could figure out how to enable support for Steam Broadcasting.

The folks over at livestreamer gave it a crack, but development for it soon died out.
(Here's the link to the livestreamer issue thread: https://github.com/chrippa/livestreamer/issues/621)

This may be a bit of an ask because it requires the user to be logged in but I'm fully happy to enter in my steam information to get it working.

Here's a link to the directory of live broadcasts: http://steamcommunity.com/?subsection=broadcasts

Hope this isn't too much of a challenge for you guys.
Cheers.
