I realize this is many months late but uhh, I just tried it with a friend of mine on a privately hosted dedicated server, both of us in VR, 100% works.
Only thing you need to do different is start the VR mod via console commands, so "vrmod_start" in console to start it.
Also recommend turning "vrutil_autostart" to 1 to make it automatically start the VR mod when it switches maps, which it also does perfectly, waiting for every player to get to the loading zone. :)

Thanks, this exactly what I wanted to know

I just tried, but after i am dead and the map gets reloaded i cant walk anymore with the left stick. when starting a new game its also impossible to walk. only thing is, when i have both controllers off when starting a new game and activate it like told on the monitor, then walking is enabled.
