I think it is kind of solved, Windows for example support remote connections via remote desktop. With the desktop version you can either run local or remote session. If you run server versions you can have multiple simultaneous connections. The same things are of course available on Linux side as well I'm doing this with Windows all the time, connecting from laptop my desktop where I have all the apps running. It's pretty usable even with 4G connections.
