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.
