That's great Tetsuya. There was some discussion on the mailing list previously on vhost-user in response to an RFC from Huawei Xie (http://dpdk.org/ml/archives/dev/2014-August/004875.html). If you're planning an additional RFC on this, that should help to progress things and to make sure we're not duplicating work.
