There's even an "easier" method: - build a two-nodes or more box with a fast network in between - code a DSM on top of it - abstract all devices (including networks, graphics[1], sound, filesystems). - make the code able to add and remove dynamically nodes
The upgrading the kernel is nothing but: - migrate all processes/threads to node 2 - detach node 1 - reboot node 1 - attach node 1 - migrate all processes/threads to node 1 - detach node 2 - reboot node 2 - attach node 2 - let schedulers flatten the load after a while
Of course do all of that while chatting with friends on IRC under X.
This is not immediate, but all the needed technologies are already out there. I think linux 3.0 will be able to do that.
