Lovely video and ingenious implementation. Kudos!

As someone managing various servers, both at home and at work, I see how this can be really useful. I see it not in the production space yet but rather in the experimenting, using a Linux machine as a second compute device!

So regarding your last point, I'm convinced. I think it is useful! The one fact that is bugging me is that now it requires a client specific app, with GUI, on my PC and I wonder if using ssh port forwarding could reduce the surface. I mean I wonder if either having a rich client that executes commands via ssh or a rich server (including Web Server) with ssh port wouldn't suffice, so that I can avoid installing stuff on the server AND on my computer.
