Okay, so, I'm working on a VR game framework to sell to devs. I've got all of the usual suspects in terms of movement such as Teleport and Thumbstick, but I've created one more that I don't think I've seen in any other VR game. I call it "MirrorStep."
The idea is that you walk to the edge of your play area and then you will hit a trigger just shy of the boundary. This will quickly fade to black, flipping your play area 180 degrees around you as the pivot point. You can then do an about-face yourself and continue walking towards your intended destination. 
Basically, you're pacing your play area back and forth in order to move forward in VR. 

This is a movement method that requires no controller input and can scale to any size world. It's intended for wireless headsets and big play areas for obvious reasons. What do you think? It feels good in testing, but I'm not sure if it's intuitive.
