Twitch today announced the Twitch Mobile Software Development Kit (SDK), which will eventually let mobile device gamers capture, archive, and live-broadcast their games to Twitch, a social network for gamers that already has a large presence on consoles and PCs.

For mobile gaming fanatics, things are about to get a whole lot more interesting.
