VR with 2 Crew? Multi-user VR enviroments question..

Is anyone aware of a VR program and/or system that allows 2 VR users on the same machine.  I work for a small airline and we are hoping to use a VR system for CPT (cockpit procedure training), where crews practice flows/SOP's before going to SIM or completing "on-wing" training in the actual aircraft.  Current CPT is completed either sitting in a plane on the ramp or in hangar (not always practical as is dependant on aircraft availability - usually only in the hangar for maintenance, cold to do outside in the winter), having to pay for extra sim sessions to do in the full motion sim (expensive $$$), or with posters pretending to push buttons on paper.  VR flight decks seems like it could be a really great option, but needs to be interactive with minimum two users and an external display for an instructor (if needed).  Thanks in advance for the help!
