I used to work at a research institute that had two campuses on either coast and we had those "iPad on a stick" type telepresence robots so people on one coast could attend (physical meetings) on the other. They eventually went away because more and more meetings either became virtual or were hybrid-virtual physical and so a laptop could work just as well as telepresence.
