I own a developer kit (DK2) Rift and AFAIK all games mirror what the wearer is seeing onto the primary monitor. Which is good for sharing an individual's experience, but doesn't do much for group experiences.

I'm pretty excited for more asymmetrical games and experiences along the lines of http://www.keeptalkinggame.com/ (which is hilariously fun). I don't own a WiiU, but I've heard it has some pretty good asymmetrical examples as well.

The SDKs are starting to support "Direct Mode," which puts the contents only on the HMD, not mirrored onto the primary. That may or may not be optional, and may or may not have a performance hit if you turn it off.

I think something like livestreaming to a Chromecast would be cool.
