I find the idea of using the most advanced VR technology for your olde command line terribly funny. All those 80s cyberpunks imagining people actually traveling through cyber-information highways, using them in combination with feedback gloves to browse and actuate on the information in a myriad ways... And we just want a command line. I'd love to go back in time to tell them that this is a major use of VR and see the abject horror in their faces.
video glasses connected to a smartphone could get you pretty close, sadly display resolution isn't great.
Maybe one could adapt cheap FPV glasses to take a smartphone instead, they don't "waste" pixels on stereo as VR setups do.
Seriously, a small VR system that's just an SSH client would be a pretty massive improvement on my life.
