He's not refering to banging the hardware from userspace (well, I wasn't
and he was replying to me)..


Though I can't imagine that it needs to be *that* high.. With a special
(non-ip, non checksummed) ethernet protocall for san's and a highly
optimized networking path much lower should be possible..

I still think my point in clear, such remote fork and migration should
workable if the migration is infrequent enough.
