Maybe I'm just missing something, but is performance considered to be the ONLY potential advantage of inter-machine process migration?
How about uses for high availability, for e.g. ? This would probably require some kind of checkpointing depending on what kind of failures we're trying to recover from, or there may be a better way to get state info migrated as well.
No?
