Not much good if you're migrating because the node's gone down. What happens then? Sorry to ask, RTFM seems a bit beyond my ken, right now. Also, that gives you a single level of checkpoint, in fact, I'd call that strictly migration, C/R should allow a history of checkpoints, each of which can be restarted. Might not be possible, of course, unless one defines the underlying platform with new properties specially designed for C/R (and migration). Hence my insistence that Plan 9 is a better platform than other OSes in common use. The hardware may need to be adjusted too, but that's where Inferno EMU will come to the rescue :-) ++L
