Hi! Fine and i am enjoying SKYBOX on Gear and Rift! :]
Yeah they certainly are things that are needed for multi since there would not be much point into it otherwise. We have used Bigscreen for watching movies with my friends and talking is the most profound things in multi but hand emotes serve very big things too! Like pointing to certain thing, high fiving, shaking your head in disbelief (this is HMD though), etc.
And Bigscreen supports Leap Motion and it has much more delicate hand emoting than controllers could ever give. After we had watched many movies together my friend also bought Leap Motion since he was frustrated about how i could do so many things with my hands that with controller you cannot.
So just a few suggestions and if you check Bigscreens Steam/Bigscreen forums you can see that emoting is pretty highly conversed.
But first let's wait for that SKYBOX multi :]
