Depending on your needs, the technology is already there. I already do most of my work in VR with my partner, while he is also in VR from his house about 2 miles away.

We need a few desktop screens up for information, a big whiteboard, and the ability to see each others screens. With Immersed and Horizon Workrooms we get all of that already. Before workrooms was really stable we were using Immersed and keeping Mural (white boarding) up on one of our desktops together.
