Boneworks has a multiplayer mod called Entanglement that's currently a work in progress, but it's very promising so far. Development seems to be a little stagnant right now, but they have working object/physics sync and even custom playermodel support. Hopefully they'll work on it some more, because the NPC/enemy sync is a little iffy right now.

Skyrim VR is absolutely wonderful if you can spend some hours installing mods for it and tweaking it. Most SSE mods work on it. Not sure how the anniversary edition will impact VR.
