This is amazing!
It would be awesome if we can try this from our Index HMDs at home. 
Idea 1:
Multiple VR users take turns controlling Reachy to paint or draw, then have the creations posted on your site, like a kindergarten class.
Idea 2:
Two Reachy robots [each controlled by different player] plays Jenga against each other.
Idea 3:
Someone will control Reachy to paint someone’s nails or apply lipstick. This might not work on the mass scale though. 
Idea 4:
Set up a hoop to play roboBasketBall. People have 1 minute to control Reachy and pick up & throw as many balls as possible. Leaderboard set afterwards.
I can go on and on but I mean, weekly demos of this would be both great exposure and loads of fun. 
Keep up the cool stuff.
