Telepresence for travel. One use case is that I don't have time to travel to location X, but would like to be part of a group who is hiking, etc there. Could see this being quadcopters with cameras with dual controls (remote for me and possible to be overridden by someone on site if there is an issue).
Second use case is my disabled daughter who I can bring back videos of places to, but it's not quite the same as sharing the moment, and of course would give her a sense of freedom to be able to zoom in and look at something I might not have thought to capture.
Given connectivity issues to many of the places I know "I" would like to be able to go to virtually, I suspect part of the problem will be convincing folks that it doesn't ruin their wilderness experience to let other folks attend virtually. Given that you would then have fewer travelers impacting the environment I would consider this a net win.
