For context, the diameter of the earth is 12,742 km. So it would take roughly 30ms to make a round trip. Assuming that a signal need only traverse half the diameter as you can take the shortest arc, you get down to ~6371km which brings you back down in the range of 15ms. I assume the 15ms was chosen for the 60fps that VR needs to run at to be considered reasonable. If so, having a local machine handle redraws would be reasonable and requiring a 30fps update on all "agents" and other world elements would probably be pretty unnoticeable by most people.
