Hmm... with standalone HMDs coming out this year, I wonder what might be the VR equivalent of linux handhelds?
HMDs based on qualcomm's snapdragon 835 vr chipset are android, so perhaps someday linux on android on HMD.
But you can also think of HMDs as merely fancy monitors. And use a bluetooth keyboard (for flexibility). Leaving you with simply a portable headless linux box. Acting as a wifi hub.[1] Serving say a WebVR RDP client to the HMD.
So imagine a standalone android HMD (like [2]), decorated with a linux single-board computer. Or several. Maybe with power from the HMD battery (~4k mAh) via USB. So power-on all, run chromium in the HMD, browse to the linux board, run Xpra RDP in stereo. For passthrough AR, one often wants more cameras and associated computes than an HMD provides out of the box (for dynamic range, and high-res narrow-FoV to see lecture slides, and fisheye for better situational awareness (eg on public transport), and optical tracking of hands and keyboard and such). So imagine a Pi-based ecosystem of linux HMD-mounted symbiotes. And any boards with their own battery, and not doing camera, can stay in a backpack or pocket, simply connected by wifi. Thoughts?

The Pockulus C.H.I.P. (http://pockulus.getchip.com) is a Linux-based headset. It's meant to be a bit silly, but it's real, it's Linux-based, and it's a headset.
