I assumed cloud computing means you can log into any node that you are authorised to and your data and code will migrate to you as needed.
The idea being the sam -r split is not only dynamic but on demand, you may connect to the cloud from your phone just to read your email so the editor session stays attached to your home server as it has not requested many graphics events over the slow link. <anecdote> When I first read the London UKUUG Plan9 paper in the early nineties I was managing a HPC workstation cluster. I misunderstood the plan9 cpu(1) command and thought it, by default, connected to the least loaded cpu server available. I was sufficently inspired to write a cpu(1) command for my HP/UX cluster which did exactly that. Funny old world. </anecdote> -Steve
