Yep, they just started doing it today. Opt-in for beta features via your account setting and you're all set.

Coincidentally, I have activated it on my account for friends to come and watch me suck at video games. If you wish, add me at MicahWeil, naturally (if you see Cobra Commander's mirrored mug, you have the right guy), and let me know who you are so I don't reject your friend request. I promise to TRY to make it entertaining...
