Dear Peter,

I have no preference for this issue, but I am just seeking the idea.

So you are *not* favor to add an initiator feature directory.
Then where do you think a target ought to send MESSAGE_REQUEST
on the initiaotr’s memory space? Also how does the target get
an address being used for this purpose?
