Personally, I don't have a real need for process migration, but I'd like to see it because of what process migration would allow. The ability of stopping a process in it's tracks, saving it to a core like file, rebooting the machine, then restoring back the process comes to mind. The occasional moving to another machine would be nice as well I suppose. I'm much less interested in the "performance" hit I'd take, as I'd only need it occasionally.
What I would be interesting to see is the ability to snapshot the entire system just before a reboot, then perhaps with a command line argument to the kernel, reload that snapshot. Obviously putting all the devices back into the right state would be problematic, but I think that it could be done. Perhaps if the drivers had additional hooks for suspend (dump its state) and unsuspend (reload state).
This might be especially useful for portables.
