I actually like that idea! An office environment that allows to move around outdoors instead of forcing a sedentary lifestyle indoors is certainly a more healthy and happy environment and an important part of any discussion of a future Internet. (So I added it to my list of ideas for a sustainable IT event.)
After a little while, it would even be acceptable that people appear in video calls while running, hiking in the woods or flying their jetsuit:
(I selected this clip because it shows how the video setup for a video conference on the go can be done. Basically the person wears a helmet camera on a stick, and because the camera is looking along the stick it’s easy to keep that stick more or less invisible. You see the stick from a side view a few seconds into the clip.)
