I think there's something elegant about doing migration in a
unidirectional stream. It makes live migration work to a file, to a
qcow2 file, etc. with no protocol change.
The ack'ing bits can be done by a live migration transport since it
happens entirely at the end of the stream. The old ssh: migration used
to do this and provided a simple means that worked 99.999% of the time :-)
